SPACE - S0 - 20210226 - Beaufort Gyre, Oceans in Trouble, New Comet

Good Morning, 0bservers!

   
    
Solar winds spent most of the day yesterday going down from their peak of 500 KPS, although they did pause for a brief rally from 430 KPS back to 500 KPS around 2000 for a couple of hours. They petered out (yes, that is a scientific term) and continued downward to their current 400 KPS reading. Particle Density also lowered a bit through the day, however Temperature readings remained mostly steady (with a brief bump upward around the same time of the speed increase). The Phi Angle was a mess most of yesterday, but it finally seemed to stabilize around midnight UTC. Despite that earlier instability, the KP-Index stayed in the green for 24 hours straight, the first time that's happened in a few days. KP-3s still dominate the chart, though, so we'll see how it goes before the next coronal hole stream impacts us, probably late Saturday through Sunday. We're mostly back to nominal readings for the Magnetometer and Proton Flux charts. The Electron Flux chart did almost breach the threshold again yesterday, but not quite enough to trigger an alert. Hopefully we'll see it back to its usual calm self tomorrow. Background X-Ray Flux readings did dip into the upper Class A flare range yesterday, but clawed its way back to Class B while chucking out a pretty strong Class C flare about 0600 UTC. From the video loop at 193Å, it appears the trailing sunspot in the North (the one that has been destabilizing) had a small intra-atmospheric release which triggered the actual flare from the sunspot group in the South. That surprised me a bit, I really thought the second Northern sunspot group (that closest to the departing lim) would have been the one to blow. The Southern coronal hole has extended upward to the equator and is now crossing the midpoint. The Northern tendril from the polar coronal hole crossed that point about midnight UTC, but it really didn't develop into much, so I don't see any real effect from that one bothering us, it would be overwhelmed by the Southern activity.
