Solar activity - geomagnetic strorm in progress

Solar wind speed: 637.9 km/sec density: 1.4 protons/cm3
Solar activity was at low levels during the period. The northeast spot area of Region 2321 (N12E02, Ekc/beta-gamma) was separated and numbered
as Region 2326 (N15E12, Cao/beta). Region 2321 remained the largest group on the disk. The largest flare was a C5/1f from Region 2324 (N18E34, Dkc/beta-gamma). Region 2322 (N12W25, Bxo/beta), and Region 2325 (N05E44, Cso/beta) were mostly stable and quiet. There were no Earth directed CMEs detected on available LASCO imagery.
Geomagnetic Storming Continued overnight.
A high speed solar wind stream continues to kick up geomagnetic activity, including a brief period of moderate (G2) storming at high latitudes. Sky watchers should remain alert for visible aurora displays once it is dark outside.
Below is a picture of one of the biggest solar prominences ever captured, June 4th 1946.
