SPACE - S0 - 20210504 - Earth Skeleton, Scary Solar Forecast, Venus Change

May The Fourth Be With You, 0bservers!

   
    
Solar wind speeds continued their rise yesterday, but it was not a severe one. Looks like it topped out just over 500 KPS around 1700 UTC, went down slightly until midnight, UTC, then peaked again at the same level. Since then it's been going back down, with a current speed of 400 KPS. Plasma Density spent the day going back down after its minor surge in the early morning hours, but around 2000 UTC it started a slow rise, not coming close to its original levels. Temperatures also reduced from yesterday's high, going back to a nominal 4900°K-5000°K range. Still seeing a lot of Phi Angle movement, but not wildly so. KP-Index readings remain calm, in the KP-1/KP-2 range, so we were able to avoid those minor geomagnetic levels that were predicted yesterday. The Magnetometer is again shallowing, so we should see it returning to normal sine wave structure in 48 hours or so, if the normal pattern holds. Proton Flux and Electron Flux levels are blissfully boring. However, we did see odd surge (not spike) in the X-Ray Flux around 1900 UTC that lasted about 3 hours, but it didn't quite make the Class B range and calmed back down to the lower end of Class A. That is, until 0900 UTC when we had a sharp spike up into the lower Class B range. There appears to be a new (small) coronal hole system developing in the South at around 50°-55°, and it's building close to the midpoint, so hopefully if it grows more it'll already be out of range before it becomes problematic. That new sunspot group in the South is now more visible on the Magnetogram and the video loops, and there is definitely magnetic separation, but at worst it only appears to be Beta complexity. We'll monitor this one as it moves closer toward the center.
