SPACE - S0 - 20210728 - Solar Eruptions, Rock Art Anomaly, LLSVP, Super Flare Star
Good Morning, 0bservers!
Well, we waited and we saw. Looks like that coronal hole stream finally arrived, because after a mostly calm day in solar wind speeds (300-340 KPS) we saw a jump to 400 KPS around 0130 and another peak to nearly 460 KPS by 0700 UTC. It seems to have calmed back down to around 400 KPS as of 1000 UTC. Particle Density started rising after midnight UTC as well, with a drop just preceding the increase in wind speeds. Expect another similar "hit" from that CME yesterday coming in the next 36-72 hours. The Temperature chart was getting up there, though, riding the 4000°K line most of yesterday before peaking out around 5400°K around 0800 UTC. The Phi Angle was still a mess most of yesterday, but it got really scrambled after midnight UTC, right before suddenly "almost" stabilizing around 0200. Whereas the Bt/Bz polarity collisions were prominent as were the variances starting around 2200 UTC. Surprisingly, the most we got off the KP-Index was a KP-4 (yellow, minor geomagnetic storm) around 0300, with the next two readings dropping down a notch back into the green. The Magnetometer tracked a high/low sine wave but we're still in nominal territory. The same is true for the Proton Flux and Electron Flux levels, and they seem to have "fixed" the gap in the latter from yesterday's report. The X-Ray Flux was certainly busier than the last few days, with a couple of flares in the upper Class B levels at 1900 UTC and 0800 UTC, and one hitting the Class C line around 2245 UTC. Caught that last one on the video loops at 131Å and 304Å, which is why I was able to hit the timestamp so closely. The Magnetogram shows a lot of complexity (not to mention spread and size) in the Southern sunspot group currently crossing the center, but the Northern sunspot group still approaching the midpoint is a lot more dispersed. The departing sunspot in the North is almost linear (at least the negative magnetic component) but the leading positive edge is more of what you'd expect.
