Large Solar Prominence in Motion Catured on 22th January 2024
Alqueva´s Dark Sky Reserve | By Year: 2024 | Solar Ha | Time Lapses Photography
Captured on the 22th of January, 2024, from Dark Sky® Alqueva region, Portugal, a high-resolution image and time lapse sequence features the chromosphere activity, revealing a large prominence in motion. It’s possible to see a lot of interesting changes on its shape. We can also notice a lot of fine spicules surrounding the solar disc, while the chromosphere itself is showing a slower motion. Even with a few high clouds which almost distroyed the sequence, I’ve manage to manually adjust the quick changes in light and keep the sequence runing to produce a time lapse of about 332 images. The final result is a 4K high resolution solar movie comprising around 2h of photos.
PT: Captada a 22 de Janeiro de 2024, na região Dark Sky® Alqueva, Portugal, uma imagem de alta resolução e sequência time lapse mostra a actividade da cromosfera, revelando uma gigantesca proeminência em movimento. É possível ver muitas mudanças interessantes em sua forma. Também podemos notar muitas espículas finas ao redor do disco solar, enquanto a própria cromosfera mostra um movimento mais lento. As condições foram muito desafiantes, mas mesmo com algumas nuvens finas que repentinamente cobriram o céu a meio da sequência, eu consegui gerir e compensar manualmente as alterações de luz drásticas para permitir continuar a sequência sem interrupções. Assim foi possível produzir um time lapse de cerca de 332 imagens. O resultado final é um filme solar de alta resolução 4K com cerca de 2h de fotos.
