Near-continuous tracking of solar #ActiveRegion NOAA 13664 over three solar rotations: https://arxiv.org/abs/2510.05979 -> "The derived time series of non-potentiality parameters, the first of their kind, far exceeded the typical 14-day window imposed by solar rotation and were remarkably consistent, exhibiting strong correlation with the flaring activity of the region."

‪Here are some great shots from our #GREGORSolarTelescope observation campaign in July. Peering into the #photosphere and #chromosphere, we caught several emerging active regions – and a #flare! This will help us study the plasma dynamics in active regions and how energy builds up to create a flare.

Hoping for a #flare: During the final days of our 2 week observation campaign with #GREGORSolarTelescope on Tenerife, scientists work remote from the “GREGOR Operations Center” at #MPSGoettingen and zoom in on a recently emerged active region that looks promising. Thanks for all the support onsite!

Monster #sunspot group #AR13780 in white light and H-alpha 6th Aug 2024. #AR13781 is also in view if you expand the images, along with another region on the limb that hadn't been named yet. White light taken with a William Optics 70mm refractor, Altair Herschel wedge + Baader continuum filter. H-alpha image taken with a Coronado PST. I used a 3 x Barlow and ASI120MC camera on both and stacked the best 50% of a 1,000 frame video #Sun #ActiveRegion

Drawing of #Sunspot #AR13615, the largest and most complex white light #ActiveRegion I've ever drawn, as it looked at 11:00 UT 24th March 2024. I created it from photos taken with a #WilliamOptics 70mm refractor, Altair Herschel wedge, Celestron 3x Barlow + ASI120MC camera. #AstronomySketch #SunSketch
