#Sunspot #AR14366 looking impressive at 12:19 UT 4 Feb '26. I had a long enough gap in the clouds to get a very quick visual look then captured a single video before the clouds swallowed the Sun again. #CoronadoPST, 2x barlow & #ASI120MC camera, best 50% of 1,742 frames #Oxfordshire UK #ActiveRegion

Emerging active region as seen by GREGOR. It's a black and white image of an area swarming with bundles of lines stacked in various orientations. Near center, one area appears especially dark compared to the surroundings.

Emerging active region as seen by GREGOR. It's a black and white image of an area filled mostly with granulation pattern, a convection-cell structure looking simular to a very unorderly honeycomb pattern. Near center, that structure is broken up and one area appears especially dark compared to the surroundings.

‪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 […]

Two scientists are seated at tables in a lab room with three small monitors in front of them and two large screens mounted on the wall. The large monitors show various monitoring images of a telescope and the data it is taking.

Zoom-in on the contents of one of the large screens: Various windos showing a full-disk magnetogram image of the Sun and two versions of a zoom onto an active region.

A zoom-in onto one of the large screens showing various context images: the observatory from a birds-eye view, its surroundings, close-ups of the telescope from different angles, and select scientific data panels.

A full view of the operations center again, from a different angle as before and this time showing the backs of three busy scientists facing various monitors both directly in front of them as well as the two large screens on the wall of the room. The scientist in the middle is busy using her mouse clicking on things, and her upright posture suggests a high level of concentration.

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 […]
