How big is big ? On 6th and 7th February, 2022, the Sun has featured a gigantic solar prominence over the limbs chromosphere. This Giant was visible for two days and then erupted, throwing a coronal mass ejection (CME) into space. So I made a huge effort of gathering as much images as possible during these two days in a row. With it, I could show the shape evolution of the prominence before it vanished. Most of the images were made between UT11h51 and UT14h39. On the first day, the weather conditions were not perfect, with moments of average seeing. The second day was much better in terms of stability. So I made 4 time lapse sequences that reveals this formation in motion, comprising a wider and close-up views for both days (with 2x barlow). The final result is a 4K high resolution solar movie comprising around 2,5 hours for each day, with a total of 5 hours of images. According to my measurements in pixels, the size of this prominence – special in the second day – was about 10x the size our planet Earth, in height, but stretching around the sun’s limb for thousands of kilometres. As comparison, a width beyond the largest system rings of Saturn. So I used my planetary images of Jupiter, Saturn and Mars to give a scale in the movie as well as in the final poster with the still images of both days. Both Solar and planetary photos were captured in the Dark Sky® Alqueva region, Portugal.
As this kind of images are involving a tremendous amount of work (several hours, days) and data to process. Here are some curiosities: I have captured 692 Raw videos of 900 frames each. A total of 622,800 frames with 3TB of space. Around 22% were used, with 138,400 still images being processed. Below is possible to watch the 4K high resolution video time lapse sequence compiling 692 shots processed (wide and Close-up), each one as result of a stack of the best 200 frames from each raw video.
