Anomalous corona - 30.3.2021 at 18.30 Vaasa Observation number 97205

Visibility III / V

Timo Alanko, Vaasan Andromeda

Anomalous frames have been reported recently, and we Ostrobothnians were also encouraged to try them on the cell. Here is one version from the ground and a little higher. In Mavic, the adjustments weren't enough to dim the image enough, but I don't think the vague perimeter around it is just the glare of the sun. The same asymmetrical shape was also present in several images. Abundant alder pollen may cause that anomalous perimeter.
