4/9 Solar Activity
4/9 p Post by Connie Howell: Sun Spot 4409 tossed a parting shot at Earth this morning from the fringes of the Sun. It’ll probably be able to do that for 2 more days, but otherwise we’ve only got 3 Sun Spots facing Earth atm and we’re mainly sitting in B Class Solar Flares.
.
We had calm Geomagnetics today, but we’ve got 2 CH HSS arriving any time now. Geomagnetic Storms are expected around midnight tonight, tomorrow night, and possible overnight 4/11-4/12. NOAA’s providing a 25% chance of Geomagnetic Storms in middle U.S. tonight, 30% chance tomorrow night, and 10% chance overnight 4-11-4/12. They’re saying the northern U.S. has a 65% chance of HP = 6 (G2) Geomagnetic Storms tonight and tomorrow night, but that’ll drop down to 40% overnight 4/11-4/12.
.
Solar Wind Speed finally fell below 400 km/sec about noon yesterday, and averaged a calm 360 km/sec today. NOAA’s expecting the imminent arrival of the CH HSS will take us back to 500+ km/sec by 4/11.
.
Electron Saturation *finally* dropped below its Alert Threshold today. It should stay there for the next 2 days, but is likely to rise to >1K pfu on 4/12 as the new CH HSSes deposit electrons into our atmosphere. Proton Saturation’s staying at Normal levels at Solar Flares decrease.

Had a rough night 4/8 sleeping, tinnitus was not as loud as earlier. During the day I had pretty good mobility and could walk normally. Even did the stairs the way I used to. Did some yard stuff. But by late afternoon I could feel something building, pain level increased and I felt restless and anxious. Overnight I was awake every 2 hours. Had a lingering sense of depression without any cause.
