Closer to the active area AR12741. Teaming up with Mr. Eric Coles.

Here is the H-alpha capture of the solar disk showing the active area AR12741 with his main spot, as it could be seen on May 14, 2019. At that time, AR12741 was a Beta-gamma region already decaying, with the light bridge that appeared a couple of days ago but on May 11, truly severing the sunspot into two distinct umbrae with a unipolar field. AR12741 was trailing some mixed fields and a few small pores that still appeared likely to lead to reconnections. The main spot has developed a light bridge which may signal that it has also come to its decay phase.

The capture is processed using the inverted mono image and false color as close to the chromatic colors specific to the H-alpha frequency. Plasma dynamics impose to shot at a high speed, so I can latter stack many frames and assure a clear, final image. It is very hard to imagine the plasma shapes because it is not solid and yet the image perfectly blends harmoniously the diffuse areas where the details are accentuated.

THANK YOU VERY MUCH, Eric, for collaboration!

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.
