A G1 (Minor) geomagnetic storm watch has been issued for 12 January (UTC day) due to a recurrent, negative polarity, coronal hole high speed stream.

The image is a composite of several different wavelengths from NASA’s Solar Dynamics Observatory. The outline indicates the coronal hole we are tracking.
