AR2759, The Biggest Solar Flare of the Year - Inverted and Colorized

This is a total reprocessing of the solar capture. Much more detail was obtained by stacking more frames and adding some AI processing to extract more surface detail.

Description from The Solar Dynamics Observatory:

The biggest solar flare of the year happened yesterday. But don't get excited; it was puny. On April 4th, NASA's Solar Dynamics Observatory captured the ultraviolet flash from new-cycle sunspot AR2759:

This is a B4-class flare. It caused only a brief and ephemeral wave of ionization to ripple through our planet's upper atmosphere. There were no radio blackouts, GPS disturbances, or satellite outages. Only during Solar Minimum would such a flare receive any attention at all.

On the other hand, perhaps "B" stands for "Bigger than you think." A typical B-class solar flare releases as much energy as 100 million WWII atomic bombs. Only on the sun, which is itself a 1027 ton self-contained nuclear explosion, would such a blast be considered "puny."

So did something big happen yesterday? Or not? Yes to both.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
