published: Tuesday, December 8, 2015 13:17 UTC UTC

A G1 (Minor) Watch is in effect for 6, 7, and 8 December as enhanced solar wind velocities from a combination of three different coronal hole high speed streams are likely to disturb Earth's magnetic field and cause minor geomagnetic storming over the next three days.
