SPACE - S0 - 20210223 - 149 Magnetic Reversals, Solar-Cycle PaleoChaos
Good Morning, 0bservers!
Solar winds have been "jumpy" to say the least, but the same is true for the other readings from the DSCOVR satellite. Speeds generally stayed in the 540-600 KPS range yesterday, slowing down to 580 KPS at the top end around midnight UTC, but then there was a massive spike to 640 KPS about two hours later before returning to yesterday's range. Density stayed mostly steady, but the Temperature ranges were a lot wider and faster than normal, only "cooling down" starting around 0600 UTC. The KP-Index was slightly calmer yesterday than the previous days, with only two KP-4 readings in the early hours. It went back into the green for most of the day and night, but we did get another minor geomagnetic storm reading right after midnight UTC. The Magnetometer readings are normalizing from yesterday, and the Proton Flux remains stable/nominal, but the Electron Flux is still pretty elevated. Looks like flare activity bounced back from a quiet day or two, with a few major jumps into upper Class B range before midnight UTC. This upped the baseline readings near the top of Class A, but then the flares were reduced to the lower part of Class B as well. Some of that flare activity seems to come from the new sunspot group in the North I mentioned yesterday (the one that developed after it passed the midpoint), but we've got a NEW grouping in the South as well. It became visible around midmorning (and wasn't showing up on the Magnetogram yesterday either, so it really "sprung up" as it were) and was already popping and outgassing. On top of that, we've got a new coronal hole group that started developing in the Southern mid-latitudes, and it's growing pretty quickly. While that looks pretty impressive on 193Å, you should really check out the 304Å loop and watch the sunspot in the South first develop and then start sparking and surging (along with the Northern one). Both of the new sunspots on the Magnetogram are showing tight spacing between positive and negative, while the older one (that hasn't yet reached central heliographic longitude) has a lot more separation between them.
