Farside Watch for January 25, 2022.

The imagery below is provided by the STEREO Ahead spacecraft. It offers a partial look at the backside (farside) of the Sun opposite of Earth, including the section that rotates onto the Earth facing east limb. The mission did also include the STEREO-Behind spacecraft to provide a wider look at the farside, however communications were lost in October 2014 due to multiple hardware anomalies.

On average it takes 13.5 days for a region to transit the farside of the Sun. The rotation rate is faster towards the equator and slower towards the polar regions.

Possible magnetic or spotted regions will appear in a white square.

CH = Coronal Hole.
