SPACE - S0 - 20210430 - Star-Planet Energy, Master the Disaster

Good Morning, 0bservers!

   
    
Solar winds stayed mostly steady in the 320-340 KPS range yesterday until around 1900 UTC, when they jumped up to about 360 KPS when the Bt/Bz polarities almost touched on the upper chart. That didn't seem to upset the Phi Angle at the same time, and speeds dropped even lower, in the 300-320 KPS range, but at last reading it has gone back up to 350 KPS. Particle Density continued to climb until around midnight UTC before leveling off, while Temperatures took a small upward bump around the same time as the speed bump but remained elevated. We did see a polarity shift in the Phi Angle around 0130-0200 UTC, now in the 180 range, but it doesn't seem to have had a negative effect on the other readings. The KP-Index remains green, with mostly KP-2 readings. Still waiting for those coronal hole streams to up those numbers a bit, but at most we should only see minor geomagnetic storms through the weekend. Magnetometer readings are nominal, with the peak and valley a bit more pronounced than yesterday, but still well within expected levels. Electron Flux readings again flirted with the alert threshold line, but don't appear to have crossed it (significantly), and Proton Flux readings remained nominal. We did see a pretty good upper-B Class flare spike on the X-Ray Flux around 2200 UTC, preceded by two smaller spikes, with another surge into lower-B Class around 0300 UTC. Background radiation has since dropped a bit lower into the A Class range. The video loops were all wonky (yes, that is a scientific term) for almost 12 hours yesterday, but it looks like they were able to fix the issue and the Sun has returned to center frame. The last of the Northern coronal hole system is passing the midpoint, where we can expect some solar wind impact in the next 48-72 hours (apart from the smaller stuff already on its way).
