International Space Station as Seen in H-alpha Crossing the Solar Disc
The image shows the International Space Station (ISS) silhouette while crossing the Sun´s disc at a distance of 436.29km from us at a speed of about 7.38km/s. The ISS completes an entire orbit around Earth each 90 minutes. Carrying on board astronauts, the large artificial satellite orbiting our planet with a width of 108.5 meters seems although very small when compared with the Solar disc with an angular size of 31.5′ is actually 29.2 times larger than the ISS in the moment of the passage. Hard to see it even with a special telescope equipped with Ha filters, only the fast video camera shutter set to an high speed frame rate could capture this rare moment that happens in a blink of an eye, as it was seen from Redondo, Dark Sky® Alqueva Reserve, Portugal, on June 6, 2021, at 13h20m11s (UT 12h20m11s) with a total duration of only 0,55 seconds. Its very interesting to recognise on the picture the ISS structure with the solar panels and main body elements well distinct. The image also shows in great detail, spicules and supergranulation in the surface of the Sun. Granules, as well as sunspots, appear in a layer we call the Photosphere (sphere of light). Being from this same surface that emerges all the light we visually see, leaving our star, it is involved in the Chromosphere (sphere of color), which is the place where we can observe gas filaments visible on the image and solar Prominences, where Solar Flares do occur. With a diameter of 1,392,000 km, our Sun is composed of 73% Hydrogen, 25% Helium and 2% from heavier elements. The image is also featuring many prominences spread around the solar limb, in the Chromospher.
PT: A imagem revela a silhueta da Estação Espacial Internacional (ISS) atravessando o sol a uma distância de 436.29km de nós e uma velocidade média de cerca de 7.38km/s. A ISS completa uma órbita em torno da Terra a cada 90 minutos. Transportando a bordo vários astronautas, este grande satélite artificial com uma envergadura de 108,5 metros parece muito pequeno quando comparado com o disco solar com um tamanho angular de 31,5 ‘ é na verdade 29,2 vezes maior do que a ISS no momento da passagem. Difícil de observá-la mesmo com um telescópio especial equipado com filtros de protecção H-alfa, só o obturador da câmara de vídeo numa sequência de disparos rápidos tem a capacidade de captar e eternizar este momento raro que acontece num um piscar de olhos, com a curta duração de apenas 0.55 segundos, como foi visto a partir do Redondo, no Dark Sky® Alqueva, Portugal, a 6 de junho de 2021, às 13h20m11s (UT 12h20m11s). Na fotografia é possível reconhecer a estrutura da ISS com os seus painéis solares e os elementos que compõem o corpo principal. A imagem também mostra a superfície supergranulada do Sol e repleta de espículas em grande detalhe. Os grânulos assim como as manchas solares, aparecem numa camada a que chamamos a Fotosfera (esfera de luz). Sendo desta mesma superfície que emerge toda a luz que vemos sair visualmente da nossa estrela, está envolta na Cromosfera (esfera de cor), sendo o local onde podemos observar Filamentos de Gás como os que são visíveis na imagem e Protuberâncias Solares, ou Proeminências, regiões onde ocorrem as chamadas “explosões solares”. Com um diâmetro de 1.392.000 km, o nosso Sol é composto por 73% de Hidrogénio, 25% de Hélio e 2% de elementos mais pesados. A imagem captada a partir do meu terraço, revela assim uma série de intensas protuberâncias que se espalham à volta do limbo solar, na cromosfera.

Large Solar Prominence Surrounding the Sun’s Disc
Captured on Februray 24, 2021, from Dark Sky® Alqueva region, Portugal, with a Solar Ha telescope – at the wavelength of Hydrogen-Alpha, the high-resolution image features a gigantic solar prominence visible around the sun´s limb at UT 14h02 (Universal Time). Due to hard conditions by that time like winds, clouds and a very unstable seeing (atmospheric stability), I couldn´t get so small scale details as I wish, although, the large scale prominence was so incredible that I had to capture it in a few videos shots, although, not enough for a time lapse which needs a long period of time with nice amtospheric conditions.
PT: Captada a 24 de Fevereiro de 2021, a partir da região do Dark Sky® Alqueva, Portugal, com um telescópio Solar Ha – no comprimento de onda do Hidrogénio Alfa, a imagem de alta resolução apresenta uma gigantesca promeminência solar visível às 14h02 UT (Tempo Universal) ao redor do limbo solar. Devido às condições difíceis desse dia, com vento, nuvens passageiras e uma atmosfera muito instável (seeing), não consegui obter detalhes numa escala tão fina como gostaria. No entanto, a proeminência que apresenta detalhes numa escala média era tão incrível que tive de registá-la em alguns vídeos, embora não tenham sido suficientes para criar um time-lapse, que precisa assim de um longo período de tempo com boas condições amtosféricas.
Above – from left to right – is possible to appreciate the color portrait of a shot taken between UT 14h02 (prominence) and 14h13 (surface), and the BW version.

Solar Chromosphere Featuring a Large Prominence 6,5 Times Larger than Earth
Captured on May 25, 2020, from my backyard near Dark Sky® Alqueva region, Portugal, around noon with a Solar Ha telescope – at the wavelength of Hydrogen-Alpha, the high-resolution image features a gigantic solar prominence visible in great detail around the sun´s limb due to an exceptional seeing conditions (very good atmospheric stability). As in average the solar disc has a diameter of 1,391,000 km, we can determine that the large prominence could reach around 83,000 km high, which means 6,5 times larger than our planet Earth with a diameter of 12,742 km. The image also shows spicules and supergranulation in the surface of the Sun. Granules, as well as sunspots, appear in a layer we call the Photosphere (sphere of light). Being from this same surface that emerges all the light we visually see, leaving our star, it is involved in the Chromosphere (sphere of color), which is the place where we can observe solar Prominences, where Solar Flares do occur. Our Sun is composed of 73% Hydrogen, 25% Helium and 2% from heavier elements. The image is also featuring other smaller prominences spread around the solar limb, in the Chromospher. To see the full report sequence with close-up shots of the large prominence, and time laspe video, click here.
PT: Captada em 25 de maio de 2020, a partir do meu terraço perto da região do Dark Sky® Alqueva, Portugal, por volta das 12h00 com um telescópio Solar Ha – no comprimento de onda do Hidrogénio Alfa, a imagem de alta resolução apresenta uma gigantesca promeminência solar visível em grande detalhe ao redor do limbo do sol, graças a condições de seeing excepcionais (excelente estabilidade atmosférica). Como em média o disco solar tem um diâmetro de cerca de 1.391.000 km, podemos determinar que esta proeminência é de facto gigante podendo atingir cerca de 83.000 km de altura, o que significa 6,5 vezes maior que o nosso próprio planeta Terra com um diâmetro de 12.742 km. A imagem também mostra a superfície supergranulada do Sol e repleta de espículas. Os grânulos assim como as manchas solares, aparecem numa camada a que chamamos a Fotosfera (esfera de luz). Sendo desta mesma superfície que emerge toda a luz que vemos sair visualmente da nossa estrela, está envolta na Cromosfera (esfera de cor), sendo o local onde podemos observar Filamentos de Gás e Protuberâncias Solares, ou Proeminências, regiões onde ocorrem as chamadas “explosões solares”. O nosso Sol é composto por 73% de Hidrogénio, 25% de Hélio e 2% de elementos mais pesados. A imagem revela ainda outras pequenas protuberâncias que se espalham à volta do limbo solar, na cromosfera.

Portrait of a Great Solar Prominence
Captured on May 25, 2020, from my backyard near Dark Sky® Alqueva region, Portugal, around UT 14:42 with a Solar Ha telescope – at the wavelength of Hydrogen-Alpha, the high-resolution image features a gigantic solar prominence visible in great detail around the sun´s limb due to an exceptional seeing conditions (very good atmospheric stability). As in average the solar disc has a diameter of 1,391,000 km, we can determine that the large prominence could reach around 83,000 km high, which means 6,5 times larger than our planet Earth with a diameter of 12,742 km.

PT: Captada em 25 de maio de 2020, a partir do meu terraço perto da região do Dark Sky® Alqueva, Portugal, às 14:42 (UT) com um telescópio Solar Ha – no comprimento de onda do Hidrogénio Alfa, a imagem de alta resolução apresenta uma gigantesca promeminência solar visível em grande detalhe ao redor do limbo do sol, graças a condições de seeing excepcionais (excelente estabilidade atmosférica). Como em média o disco solar tem um diâmetro de cerca de 1.391.000 km, podemos determinar que esta proeminência é de facto gigante podendo atingir cerca de 83.000 km de altura, o que significa 6,5 vezes maior que o nosso próprio planeta Terra com um diâmetro de 12.742 km.

High Resolution Image and Video Shows a Gigantic Solar Prominence in Motion
Captured on May 25, 2020, from my backyard near Dark Sky® Alqueva region, Portugal, with a Solar Ha telescope – at the wavelength of Hydrogen-Alpha, the high-resolution image features a gigantic solar prominence visible in great detail around the sun´s limb due to an exceptional seeing conditions (very good atmospheric stability). The sequence of close-up captures were taken between UT 13h41 and UT 16h00 (Universal Time) when the seeing was more stable to help reveal very interesting changes in shape, intensity and detail, with minor eruptive prominences appearing around the limb. The full disc image, captured around noon, also shows the large prominence visible at the right northern edge of the Sun. As in average the solar disc has a diameter of 1,391,000 km, we can determine that the large prominence could reach around 83,000 km high, which means 6,5 times larger than our planet Earth with a diameter of 12,742 km. To see a comparison with NASA images taken by SDO – Solar Dynamics Observatory, at approximately the same time and date, take a look here.
PT: Captada em 25 de maio de 2020, a partir do meu terraço perto da região do Dark Sky® Alqueva, Portugal, com um telescópio Solar Ha – no comprimento de onda do Hidrogénio Alfa, a imagem de alta resolução apresenta uma gigantesca promeminência solar visível em grande detalhe ao redor do limbo do sol, graças a condições de seeing excepcionais (excelente estabilidade atmosférica). A sequência de captações em close-up foi feita entre UT 13h41 e UT 16h00 (Tempo Universal), nos momentos de maior estabilidade astmosférica, para assim permitir revelar mudanças muito interessantes na forma, intensidade e detalhe da grande protuberância, assim como das pequenas proeminências eruptivas que aparecem e desaparecem rapidamente ao redor do limbo. A imagem completa do disco, captada por volta do meio-dia, também mostra a grande proeminência visível no contorno direito norte do sol. Como em média o disco solar tem um diâmetro de cerca de 1.391.000 km, podemos determinar que esta proeminência é de facto gigante podendo atingir cerca de 83.000 km de altura, o que significa 6,5 vezes maior que o nosso próprio planeta Terra com um diâmetro de 12.742 km. Para ver uma comparação com as imagens da NASA obtidas pelo SDO – Solar Dynamics Observatory, aproximadamente à mesma data e hora, clique aqui.
To help reveal the prominence flames in motion, I made a time lapse compiling 27 shots processed, each one as result of a stack of the best 250 frames from each raw video. The final result is a 2K high resolution time lapse movie from the images captured between UT 13h41 and UT 16h00. Due to vimeo algorithms it may shows a little compression, which is not visible in the .mov master file. Don´t forget to put to sound on.
PT: Para ajudar a revelar as chamas da proeminência em movimento, fiz um time lapse compilando 27 captações processadas, cada uma como resultado de um stack dos melhores 250 frames de cada vídeo raw. O resultado final é um filme time lapse de alta resolução de 2K a partir das imagens captadas entre UT 13h41 e UT 16h00. Devido aos algoritmos do vimeo, o video poderá mostrar alguma compressão, que não é visível no ficheiro master original .mov. Não se esqueça de colocar o som ligado.

Solar Chromosphere in Great Activity
Recently the Sun as featured a small group of sunspots belonging to the new Solar cycle 25, indicating a new growing cycle of its activity. The image captured from my backyard last December 3, 2020 around non with a Solar Ha telescope – at the wavelength of Hydrogen-Alpha – reveals an active surface showing three Active Regions named AR2790, AR2786 and AR2785. Near the sunspots (here seen as white dots due to the inversion) is also visible some plages (visible here as bown dark areas). The image also shows in great detail, spicules and supergranulation in the surface of the Sun. Granules, as well as sunspots, appear in a layer we call the Photosphere (sphere of light). Being from this same surface that emerges all the light we visually see, leaving our star, it is involved in the Chromosphere (sphere of color), which is the place where we can observe gas filaments visible on the image and solar Prominences, where Solar Flares do occur. With a diameter of 1,392,000 km, our Sun is composed of 73% Hydrogen, 25% Helium and 2% from heavier elements. The image is also featuring many prominences spread around the solar limb, in the Chromospher.
PT: Indiciando um novo ciclo crescente da sua actividade (ciclo Solar 25) a imagem que captei no passado dia 3 de Dezembro de 2020 por volta do meio-dia com um telescópio Solar Ha – no comprimento de onda do Hidrogénio Alfa – revela uma superfície muito activa mostrando três Regiões Activas nomeadas de AR2790, AR2786 e AR2785. Perto das manchas solares (aqui vistas como pontos brancos devido à inversão) também são visíveis algumas “praias solares”, regiões brilhantes na cromosfera situadas próximo das manchas (vistas na imagem como áreas escuras devido à inversão). A imagem também mostra a superfície supergranulada do Sol e repleta de espículas em grande detalhe. Os grânulos assim como as manchas solares, aparecem numa camada a que chamamos a Fotosfera (esfera de luz). Sendo desta mesma superfície que emerge toda a luz que vemos sair visualmente da nossa estrela, está envolta na Cromosfera (esfera de cor), sendo o local onde podemos observar Filamentos de Gás como os que são visíveis na imagem e Protuberâncias Solares, ou Proeminências, regiões onde ocorrem as chamadas “explosões solares”. Com um diâmetro de 1.392.000 km, o nosso Sol é composto por 73% de Hidrogénio, 25% de Hélio e 2% de elementos mais pesados. A imagem captada a partir do meu terraço, revela assim uma série de intensas protuberâncias que se espalham à volta do limbo solar, na cromosfera.

The Sun Surface Revealed in Hydrogen-Alpha
Recently the Sun as featured a small group of sunspots belonging to the new Solar cycle 25, indicating a new growing cycle of its activity. The image captured from my backyard last April 19th, 2020 with a Solar Ha telescope – at the wavelength of Hydrogen-Alpha – reveals an apparently calm surface, devoid of sunspots. However, thanks to an exceptional seeing (very good atmospheric stability) it was possible to register the granulated surface of the Sun in great detail. These granules, as well as sunspots, appear in a layer we call the Photosphere (sphere of light). Being from this same surface that emerges all the light we visually see, leaving our star, it is involved in the Chromosphere (sphere of color), which is the place where we can observe gas filaments and solar Protuberances, or Prominences, where Solar Flares do occur. With a diameter of 1,392,000 km, our Sun is composed of 73% Hydrogen, 25% Helium and 2% from heavier elements. The image thus reveals a large prominence visible on the left side of the disc (imagining a clock, it would be where it marks 9h) and other small prominences spread around the solar limb, in the Chromosphere.
PT: Embora o Sol tenha revelado recentemente um pequeno grupo de manchas pertencentes ao novo ciclo Solar 25, indiciando um novo ciclo crescente da sua actividade, a imagem que captei no passado dia 19 de Abril com um telescópio Solar Ha – no comprimento de onda do Hidrogénio Alfa – revela uma superfície aparentemente calma, desprovida de manchas solares. Contudo, graças a um seeing excepcional (muito boa estabilidade atmosférica) foi possível registar com grande detalhe a superfície granulada do Sol. Estes grânulos assim como as manchas solares, aparecem numa camada a que chamamos a Fotosfera (esfera de luz). Sendo desta mesma superfície que emerge toda a luz que vemos sair visualmente da nossa estrela, está envolta na Cromosfera (esfera de cor), sendo o local onde podemos observar Filamentos de Gás e Protuberâncias Solares, ou Proeminências, é a região onde ocorrem as chamadas “explosões solares”. Com um diâmetro de 1.392.000 km, o nosso Sol é composto por 73% de Hidrogénio, 25% de Hélio e 2% de elementos mais pesados. A imagem captada a partir do meu terraço, revela assim uma protuberância grande visível à esquerda (imaginando um relógio estaria onde marca as 9h) e outras pequenas proeminências que se espalham à volta do limbo solar, na cromosfera.
