Solar Time Lapse of a Large Prominence Releasing a CME
Alqueva´s Dark Sky Reserve | By Year: 2022 | Solar Ha | Time Lapses Photography
On 22th February, 2022, the Sun has featured a gigantic solar prominence over the chromosphere, throwing a coronal mass ejection (CME) into space. This was my most stressful and lucky capture. As soon as I realised that the prominence was growing so fast and drastically, I had to quickly decide what to do. So I decided to interrupt the first sequence and rotate the camera framing again for the new composition, to be able to keep capturing this growing giant ejection. It’s the highest “flame” I saw and record until now. So tall comparing the Sun’s disc that we could fit probably dozens of planet Earths inside. Seeing was good, not perfect, but nice enough for a time lapse. So I made a huge effort of gathering as much images as possible. The sequence was captured between UT11h58 and UT14h16. The final result is a 4K high resolution solar movie comprising around 2hours and 15 minutes, captured from the Dark Sky® Alqueva region, Portugal. Here is the animations from NASA SDO and LASCO-c2 (Cactus CME detection) from this same day, showing the same giant as seen from the probe in Space.
PT: Em 22 de fevereiro de 2022, o Sol apresentou uma proeminência gigantesca visível sobre a cromosfera, lançando uma ejeção de massa coronal (CME) no espaço. Assim que me apercebi que a proeminência estava a crescer de forma tão rápida e drástica, tive que decidir rapidamente o que fazer. Então decidi interromper a primeira sequência e girar a câmara para redefinir o novo enquaramento, e poder assim continuar a captar o crescimento dessa ejeção gigante. Esta foi a “chama” mais alta que vi e gravei até agora. Tão alta que caberiam provavelmente dezenas de planetas Terra na sua extensão. A estabilidade da atmosfera não estava perfeita, mas suficiente para permitir registar um time lapse. Então fiz um esforço para reunir o máximo de imagens possível. A sequência foi captada entre UT11h58 e UT14h16. O resultado final é um filme solar 4K de alta resolução com cerca de 2 horas e 15 minutos, captado na região do Dark Sky® Alqueva, Portugal. Aqui poderá ver uma animação da NASA SDO e LASCO-c2 (detecção de Cactus CME) deste mesmo dia, mostrando a mesma proeminência e CME vista da sonda que se encontra no espaço.

Important Note | Nota Importante: Never look and point a telescope or any other optical equipment directly to the sun without a proper and specialized safty filters! It can blind you forever. PT: Nota Importante – Nunca aponte um telescópio ou qualquer equipamento óptico directamente para o sol e observe através dele sem filtros especializados e seguros. Causará cegueira irreversível!
