A collection of sunspots visible in early September has rotated around the Sun in two weeks and made its way back to the Earthside of the disk (AR3105-3107). Below you can see how it appeared over the southern limb during the past week from September 19 to 23, 2022.

The active sunspots bring a chance of solar flares that could impact on the Earth's magnetic field since they are now oriented towards the Earth. Geomagnetic storms occur frequently during the equinoxes, so September is a good month to chase Aurorae in the northern latitudes!
During the daily observations at the CESAR Helios Observatory, we can sometimes witness wildlife at the ESAC site... including curious transits such as the one below:
