Solar Activity

Laboratory of X-ray Astronomy of the Sun

 

After a prolonged bout of the "heartbeat" type of reading (image below), the Solar Flare chart returned to registering the more-usual activity on 16 October 2023 (image above). Interestingly, the "heartbeat" reading started on 1 September, lasting for exactly 1.5 months. Although I can't be completely certain, this "heartbeat" reading could be the longest session that I can remember ever since I started tracking Solar activity some years back.

"Sun activity for October 20-21, 2023. This animation shows a filament eruption from earlier today (at 00:24 UTC on October 21) and then a prominence eruption off the southwest limb (edge) at 8 UTC on October 21. Filaments and prominences are the same thing. They’re both ropes of solar material and magnetic fields, arcing up from the visible surface of the sun. But we see filaments on the sun’s disk, and prominences leaping out from the sun’s edge, many times larger than Earth!"
