SPACE - S0 - 20210702 - Extinction Events, Pearls in Space, Solar Forcing
Good Morning, 0bservers!
Apologies for not posting the past few days, had a few hectic mornings/days at work of late. Also, Martha's A/C went bust again, so we've been arranging safe quarters as well as replacement equipment.
We saw a minor coronal hole stream impact Earth late Wednesday, pushing solar wind speeds above 500 KPS. It stayed in the 450-500 KPS range for most all of yesterday, but is starting to calm back down toward 400 KPS as of the 1000 UTC readings. Particle Density remained mostly steady after the Wednesday morning drop, with only a slight build later that day and a mostly smooth decline since. Temperatures appear to have followed that same pattern. Naturally, there was a lot of Phi Angle and Bt/Bz instability on Wednesday, but that also seems to have stabilized, with only a couple of perturbations around 2000-2200 UTC yesterday. Oddly enough, the coronal stream only produced a couple of KP-4 readings (minor geomagnetic storm) late Wednesday night, and the KP-Index has remained in the green ever since. The Magnetometer had a pretty jagged sine wave pattern during the stream, but is back in nominal range and shallowing. Proton Flux and Electron Flux readings also show nominal. The X-Ray Flux showed two Class C flares, one on top of the other, on Wednesday afternoon, but since then it's been mostly staying in mid-Class B with only a few small spikes here and there. The video loops are showing an equatorial coronal hole passing the midpoint right now, which means we'll feel the effect of that by Monday. The other wavelengths are showing sparking and small surges on the departing Southern sunspot group, but the incoming group in the North also appears active, if only to a minor level so far. Both of them, as opposed to the other two sunspot groups, are showing good size as well as Beta-Gamma-Delta complexity.
