SPACE - S0 - 20210221 - Tsunami of Fire, Solar Eruption, Climate Hits

Good Morning, 0bservers!

   


    
We've got a messy solar report this morning. Look at the charts yourself and you too will say "yeah, that's a mess". Let's start with the Particle Density, which stayed pretty steady over the day and night. Temperatures went up a bit but stayed steady through the period. So, how is this messy? Well, when those two indicators are steady, you expect the solar wind speed to also be steady. Uh, NOPE! It had an early jump in the morning yesterday above 500 KPS, but around 1100 UTC it decided to go up to over 600 KPS, staying between 550-600 KPS up until now. The Phi Angle seems to have been the catalyst for the speed jump, but then it too stayed mostly steady after that. The KP-Index, however, was a mickle-muckle, as the day, night and morning were predominated by a prolonged KP-4 (minor geomagnetic storm) readings. The Magnetometer was also a bit wonky (yes, that's a scientific term) with another high above 120 nanoTeslas and then a very jagged downward slope just touching the 40 nT line. The Electron Flux also breached its warning threshold for the first time in weeks. About the only nominal thing on the weather page was the Proton Flux, which remained thankfully dull. The X-Ray Flux wasn't too flare-y, but it remained with the X-Ray baseline remained in the middle of the Class A flare range. There were a couple of spikes showing on the chart, but they didn't breach the Class B line. The video loop at 193Å was far too busy, starting the previous 24-hour period (about half the loop) with a plasma filament coming up from the Southern polar coronal hole and causing a cascade collapse for a good quarter of the visible Southern hemisphere. FYI, Ben Davidson predicted this yesterday, and he was right on the money. It did produce a CME, and we may indeed catch a part of that by midweek. We also saw an intra-atmospheric release just below the Northern sunspot group. No actual flaring, but it was still a hot mess.
