May 15 2024 Observations. X2.99 Flare and Loops!

Post by DeepSolar64 »

Upon awakening this morning I found a SpaceWeatherLive alert on my phone stating that an X3.48 flare had taken place during the night coming from our old departed friend AR13664 which has now passed just beyond the SW limb. After getting dressed, checking on dad and feeding the cats I started setting up for this morning's solar session when I got the first ping from SWL concerning another flare. And it looked like an X-Class! And I had the scope already out and ready. This flare however was not from AR13664 but from a new unlabeled system on the SE limb. Getting the SMII60SS on it I could see what appeared to be a low bright sloped growth on the SE limb. SWL has this one listed as X2.99 so I was rather happy. However with the event being on the limb the flare itself is not easy to see. That sloped growth was the ejecta heated to incandescence by the flare beneath it and it was expanding rapidly into post flare loops! In minutes I could see the individual loops as they grew taller, rounder and spread out. I wish I would have set up for imaging today! At one point the loops looked double! I observed them from 14:45 until 16:45 UTC. Two hours. I used my Coronado SolarMax II 60 in single stack at 16x, 21.5x, 33x and 50x. The skies were partly cloudy. The temperature at the end of the session was 77F ( 25C ) The fainter loops from the earlier X3.48 flare from AR13664 just beyond the SW limb was still visible.

Even though I did not image I simultaneously accessed data and images online using my iPhone and computer concerning the ongoing event. Especially the NSO GONG network and the NASA SDO. That data certainly assists me with what I see in the eyepiece. I saved much of it for reference.

I wish flares could accurately be predicted ahead of time. I would have my camera on my SMII90 waiting for them!

Below are the saved images.

Hi James, great description! I'm glad you saw it. In the green SDO pictures, these flares look like the Sun turned on the turn signal.

VIvan,
Thanks. I often wonder how good I do on posting my observations. That is good to hear. 👍🏻😊

Mark,
I look forward to seeing your images!

Ivan,
Flares are certainly brighter in the far UV spectrum that the SDO images in. Thanks.

James
