5/24 from Connie Howell

It looks like a small CME came through around noon today It temporarily dropped Solar Wind Speed <300 km/sec and raised Solar Wind Density >10 0/cm3, and pulled enough electrons out of our atmosphere to drop Electron Saturation below its Alert Threshold this evening (finally!) As of this post Solar Winds are comfortable with Solar Wind Density ~5 0/cm3 and Solar Wind Speed ~340 km/sec

Good News – NOAA’s expecting Solar Wind Speeds to stay comfortable tomorrow Not So Good News – NOAA’s expecting Electron Saturation to cross its Alert Threshold each of the coming 3 days Not So Good News – NOAA’s expecting the incoming CH HSS to raise Solar Wind Speeds beginning late 5/26 Good News – NOAA’s not expecting the incoming CH HSS to cause Geomagnetic Storms

Solar Flares stayed in the B- to C-Class range today We have one Exiting Sun Spot, and 1 incoming Sun Spot that are ranked for C Class Solar Flares at this time
