A giant blob of plasma was ejected off of the Sun last night following the M4.4 solar flare off the southeast limb. Here the planet Earth is inserted for an approximate size reference. Feeling small yet? Imagery by the Solar Dynamics Observatory (SDO).

Moderate (G2) Geomagnetic Storm Watch.
The big coronal hole last seen in March is now set to face Earth once again. A high speed solar wind stream flowing from this zone is expected to reach Earth by April 21st. Minor (G1) to Moderate (G2) geomagnetic storming is expected. Aurora sky watchers should be alert beginning Monday.
