Solar Update
The sun is currently void of visible sunspots and solar activity should continue on at very low levels.

A small coronal hole is facing Earth today and a minor geomagnetic disturbance may be possible by March 19th when an elevated solar wind stream reaches our planet. Geomagnetic storming is not currently expected however.

Geomagnetic Storm Watch
A weak coronal mass ejection (CME) observed leaving the sun on March 8th is predicted to possibly reach Earth within the next 24 hours. If so, minor (G1) geomagnetic storming will be possible at high latitudes. Aurora sky watchers should be alert during the next few days.

UPDATE: The solar wind stream flowing past Earth remains at quiet levels. A minor (G1) geomagnetic storm watch was in effect for Monday due to a weak double CME event observed on March 8th. It is possible that the slow moving and relatively narrow plasma cloud missed our planet or was too weak to really notice. Active conditions will remain possible in the days ahead due to a narrow coronal hole now facing Earth.

Solar Wind Reaches Earth
Good morning. Region 2734, the lone spotted region on the visible disk, managed to produce a minor C1.3 flare peaking at 03:19 UTC (March 8). Although not a noteworthy event as far as peak X-Ray strength, the flare was associated with an eruption and what appears to be a faint coronal mass ejection (CME). A Type II Radio Emission with an estimated velocity of 683 km/s was detected. Although much of the plasma was likely reabsorbed, some did manage to escape the sun when viewing coronagraph imagery courtesy of the STEREO Ahead spacecraft. More updates to follow once an updated CME tracking model becomes available. Video below courtesy of the Solar Dynamics Observatory (SDO).
