Burj Khalifa Filaprominence Captured with Soleye 300 Dual-band on 26th November 2025
Captured with giant Soleye 300 dual-band on 26th November 2025, the image reveals a prominence resembling the Burj Khalifa in Dubai. The video comprises 148 sequences captured during about 1h revealing the motion of this filaprominence, which means a Prominence that is also a Filament, visible in the lower edge of the solar surface. I hope you enjoy the short video presented here. The image was captured from Dark Sky® Alqueva, Portugal.
PT: Captada com o gigante Soleye 300 de banda dupla a 26 de Novembro de 2025, a imagem revela uma proeminência que na sua forma se assemelha ao Burj Khalifa no Dubai. O vídeo é composto por 148 sequências captadas ao longo de aproximadamente 1 hora, revelando o movimento desta filaproeminência, ou seja, uma proeminência que é também um filamento, visível no bordo inferior da superfície solar. Espero que gostem do breve vídeo aqui apresentado. A imagem foi captada a partir do Dark Sky® Alqueva, Portugal.

A Nice Prominence Visible on the Solar Limb Captured with Soleye 300 Dual Band
Captured with giant Soleye 300 dual-band, the image reveals a prominence full of activity. Clouds came in, so I was not able to capture a long time lapse this time, but I move forward and process only this one I’m sharing today! In less than an hour due to the interaction between magnetic fields the left prominence totally vanished. The image was captured on 6th September 2025, at UT21h21 from Dark Sky® Alqueva, Portugal.
PT: Captada com o gigante Soleye 300 de banda dupla, a imagem revela uma proeminência repleta de actividade. As nuvens vieram em força nesta sessão solar, por isso não consegui captar um time lapse suficientemente longo para produzir um video, no entanto processei a melhor imagem dessa sequência! Em menos de uma hora, devido à interação entre campos magnéticos, a proeminência esquerda desapareceu por completo. A imagem foi captada no dia 6 de setembro de 2025, às 21h21 UT, a partir do Dark Sky® Alqueva, Portugal..

Solar Chromosphere Revealing a Plasma Eruption of Fine Lines and a “Surface Shaped Like Braids of Hair”
After doing the first tests on the photosphere, I’ve prepared Soleye 300 to look into the chromosphere and fortunately I caught this beautiful AR close to the solar limb during a small eruption while it was featuring a great display of fine lines of plasma. Over the disc, which I will call “surface” the image was revealling intricate shapes and depressions resemble braids of hair while small filaments, maybe reminds me the curves of snakes. The image was captured on 15th June 2025, at UT13h37 from Dark Sky® Alqueva, Portugal.
PT: Após realizar os primeiros testes na fotosfera, preparei o Soleye 300 para observar a cromosfera e, felizmente, captei esta bela AR perto do limbo solar durante uma pequena erupção, enquanto este apresentava uma bela exibição de finas linhas de plasma. Sobre o disco, a que chamarei “superfície”, a imagem revelava formas e depressões intrincadas que faziam lembrar tranças de cabelo, enquanto pequenos filamentos, me recordam as curvas elegantes das serpentes. A imagem foi captada no dia 15 de junho de 2025, às 13h37 UT, aprtir do Dark Sky® Alqueva, Portugal.

Solar Photosphere – Convective Cells Surrounding Sunspot AR 4114 Reveals Different Shapes, Sizes and Elongation
This is the first light of Soleye 300 dual-band on the photosphere, revealing the shape of convective cells – granulation – in continuum emission with Baader Calcium GENII (Ca-K 5nm filter). The image shows a close-up of a group of sunspots named as Active Region 4114, and if you notice carefully they are surrounded by hundreds of granules. Ground seeing has a role on allowing us to achieve the diffraction limit of the telescope and this is yet far from from its maximum power resolution, but I’m excited to the level of detail just in poor-average seeing conditions, as it seems to be very promising. What are then these Granules? The 4 cropped images at 100% zoom visible below, can easily help to understand the explanation by Dr. Jan Jurcák, from the Astronomical Institute of the Academy of Sciences of the Czech Republic:
“The solar surface is constantly heated from deeper layers. The heating is provided in the form of bubbles of hot material that rise convectively through the sub-surface layers. These convective cells are called granules and appear as bright dots on the solar surface. Their typical size is around 1000 km. Granules are sensitive to the presence of magnetic field. Their shapes, sizes and lifetimes are highly dependent on the magnetic field properties. With increasing field strength, the granules become smaller. In the extreme cases of sunspots, the magnetic field is strong enough to suppress convective motions, the solar surface cools down considerably and appears dark compared to its surroundings. The magnetic field is strongest in the darkest regions, but its presence can be recognised also in other areas, where the granules are smaller, brighter, or very elongated, and in the myriad of tiny bright points sitting in between the granules.“ These images were captured from Dark Sky® Alqueva, Portugal.
PT: Esta é a primeira luz do novo telescópio solar Soleye 300 dual-band, e que mostra a fotosfera constituída por células convectivas – granulação – em emissão contínua e captada com o filtro Baader Calcium GENII (filtro Ca-K de 5 nm). A imagem mostra um grande plano de um grupo de manchas solares denominado Região Activa 4114, e se observar atentamente, estão rodeadas por centenas de grânulos. O seeing terrestre tem um papel fundamental ao permitir atingir o limite de difração do telescópio, e embora nestas imagens esse limite ainda esteja longe do seu máximo poder resolvente, o nível de detalhe mesmo em condições de visibilidade média-baixa, é surpreendente e bastante promissor. Mas de que se tratam então estes grânulos tão difíceis de captar a partir da Terra? As 4 imagens recortadas com zoom a 100%, visíveis abaixo, podem facilmente ajudar a compreender a explicação do Dr. Jan Jurcák, do Instituto Astronómico da Academia de Ciências da República Checa:
“A superfície solar é constantemente aquecida por camadas mais profundas. O aquecimento é fornecido sob a forma de bolhas de material quente que sobem convectivamente através das camadas subterrâneas. Estas células convectivas são designadas por grânulos e aparecem como pontos brilhantes na superfície solar. O seu tamanho típico é de cerca de 1000 km. Os grânulos são sensíveis à presença de campo magnético. As suas formas, tamanhos e tempos de vida são altamente dependentes das propriedades do campo magnético. Com o aumento da intensidade do campo, os grânulos tornam-se mais pequenos. Nos casos extremos de manchas solares, o campo magnético é suficientemente forte para suprimir os movimentos convectivos, a superfície solar arrefece consideravelmente e parece escura em comparação com o ambiente circundante. O campo magnético é mais forte nas regiões mais escuras, mas a sua presença pode ser reconhecida também noutras áreas, onde os grânulos são mais pequenos, mais brilhantes ou muito alongados, e na miríade de pequenos pontos brilhantes situados entre os grânulos. Estas imagens foram captadas por mim a partir do Dark Sky® Alqueva, Portugal.
Above 4 different crops from the original 100% image, are showing the convective cells in detail, revealing different shapes, sizes and elongation, each one with an average size of 1000km. PT: Acima, 4 cortes diferentes da imagem original a 100% mostram as células de convecção em detalhe, revelando diferentes formas, tamanhos e alongamentos, cada uma com um tamanho médio de cerca de 1000 km.
