SPACE - S0 - 20210427 - More CMEs Erupt, Super-Flare Confirmations, Earth Rotation Glitches
Good Morning, 0bservers!
Solar wind speeds started out yesterday around 480 KPS, but they encountered a lot of swing from 0500-1400 UTC due to the messed up Phi Angle readings, which had them jumping up and down in the 440-480 KPS range, at which point they climbed above 520 KPS (still remaining variable). Around 0200 UTC there was another Phi Angle shift to stability, which caused a brief spike in Particle Density and a deep drop in speed, before restabilizing to the 460-500 KPS range. Particle Density, for its part, remained mostly steady and low yesterday and this morning except for that sort of double-jump (two hours apart) mentioned above. Temperatures also remained steady (above 5000°K) for the period, with one solitary upward jump due the the Phi Angle. The two previous early morning reports on the KP-Index (0300-0600 UTC) showed minor geomagnetic storms, but since that point we've been in the green, the latest reports showing KP-3 readings. The Magnetometer readings are a nominal sine wave structure today, and the Proton Flux/Electron Flux are also well within norms. There was a brief X-Ray Flux spike into the Class C flare range yesterday around 0300, with a couple more Class B spikes before and after noon UTC, but since then the readings have stabilized, with background radiation riding the line of Class A. No obvious surges or spikes on the video loop at 193Å, but there did seem to be some intra-atmospheric releases near the South Pole. The large cluster of coronal holes in the North are now passing central heliographic longitude, and that nasty-looking pair of sunspots are well past the center, but still a risky affair. The Magnetogram seems to show they're starting to merge into one, with Beta-Gamma-Delta complexity and a latitudinal layout. We're still at risk from a strike should that system (at least 20 planetary diameters in length) decide to get nasty.
It's been a long week, folks. Nearly 80 hours again for the On-Call period. Exhausting yet exhilarating. Still, I feel like I need a nap - until Thursday... ;)
