The Sun on June 19, 2024 - it "bubbles" south of the equator

The Sun on June 19, 2024 - it "bubbles" south of the equator

Maybe the Sun is happy that we on earth will soon celebrate the summer solstice of 2024. In many cults and cultures of our species, this event is an occasion for celebrations - the champagne corks pop and it bubbles and foams in the glasses.

On the southern hemisphere of the Sun's surface we have also been observing a real "bubble" for a few days now: The active region AR13713, which was visually inconspicuous until recently - just to the left above the currently largest and, for some time, impressively detailed region AR13712 - thrilled by constantly emerging and rapidly changing small sunspots - it "bubbles"!

This development can be followed very well over a few days on solarmonitor.org in all possible spectrums and frequencies. Visually on the Dobsonian - of course with the absolutely necessary solar filter - it is actually a feast for the eyes to follow these changes live.

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.
