SPACE - S0 - 20210901 - Sun Triggers Geomagnetic Quakes, Top Risk Zones, Space Mysteries
Good Morning, 0bservers!
Solar Wind speeds dropped after 1400 UTC and stabilized, riding the 320 KPS line up to the last reporting time of 1000 UTC. Particle density continued its mild morning rise, took a minor jump for about two hours at 1400 UTC, and then stabilized again for the remainder of the period. Temperatures moved above 5200°K, again at around 1400 UTC, but started a slow decline to the 5000°K-5100°K level, dipping below that in the early hours of this morning before returning to that region. The Phi Angle was influenced a couple of times by some polarity collisions, but both it and the Bt/Bz activity seemed to return to a nominal level. KP-Index readings moved down a bit from yesterday's KP-3 highs in the early morning hours, with mostly KP-2s and KP-1s, so no evidence of geomagnetic stress there. However, NOAA is still forecasting a KP-5 (minor geomagnetic storm) at 2100 UTC followed by a possible KP-6 (moderate) before moving back to the green range. Well, we'll see. The Magnetometer again dipped to the 40 nT level around 0800 UTC for the second day in a row, but its peak was lower than the previous two. Proton Flux? Nominal. Electron Flux? Nah, not so much. It's still cresting above the alert threshold, with its last foray over the line only an hour before this writing. There were a number of repeated spikes in the X-Ray Flux chart at the upper Class B level yesterday afternoon and early evening, but it calmed for several hours before popping one out just above the Class C line at 0930 UTC. By the bye, I misjudged the rotational speed of that coronal hole yesterday. Wasn't expecting it to start its transit across the midpoint until this afternoon at the earliest, but the video loops show that happening now. The Class B spikes I mentioned earlier seem to be coming from both the old and departing Southwest sunspot group, and a newer one crossing the Northeast lim. You can also see some prominences and a small filament release at the Southwest lim ahead of the sunspot. Too soon to see the Class C eruption, but you'll have your best chance later this morning at 304Å and 131Å. The Magnetogram shows some lessening of complexity in the departing sunspot group, and the new one incoming looks to be Beta to Beta-Delta at this point and is far smaller.
