Ok, so, I’ve reported NOAA’s forecast numbers in chart below, but tbh, I rather anticipate we’re gonna have brief HP = 5 (G1) Geomagnetic Storms overnight 4/29-4/30 with the new CH HSS. I also rather anticipate NOAA will adapt their forecast to say that tomorrow…
.
Solar Flare activity’s calmed quite a bit from what it was a coupe days ago. An Incoming Sun Spot spewed the M Class Solar Flare today. The Earth- facing Sun Spot provided lots of C Class Solar Flares, and in 3 more days it’ll likely be tossing M Class Solar Flares again as it enters its Farewell Volley position.
.
Geomagnetics were calm today, I expect they will be again tomorrow, I’ve already commented on my thoughts for overnight 4/29-4/30…
.
Solar Wind Speed’s got quite a bit of variability, but it’s averaging pretty close to 450 km/sec. It looks like the CME is losing strength, and the CH HSS that raised Solar Wind Speed is out of range, so I expect Solar Wind Speed will drop below the 400 km/sec range tomorrow. However, it’ll rise again sometime late 4/29 after the next CH HSS arrives…
.
Electron Saturation dropped below its Alert Threshold last night, and it stayed there today thanks to the CME being mixed in with the CH HSS. NOAA’s expecting it to climb above its Alert Threshold each of the coming 3 days, but if Solar Wind Speed drops tomorrow, Electron Saturation will likely stay below its Alert Threshold until 4/30. Proton Saturation’s holding steady at Normal levels.

overnight was restless, could not go to sleep until 2 am, despite being very tired, and taking my sleep supplements. Was awake off and on once I went to sleep. Woke up about 6 am and could hardly walk. From the waist down I felt like stiff, wet cement. High pitched tinnitus as well.
