Sun images from Melbourne 20 March 2023

It was meant to be cloudy yesterday but we were surprised when the clouds started to clear mid morning. Although the conditions were not great and it was quite windy, we set up and were able to get a few images in before things deteriorated further. It was good to capture some of the new incoming regions.
The seeing was ordinary at an average of 3.0 arc seconds with a standard deviation of 0.8
We took a Ha full disk two panel mosaic, then a full disk in 393nm and finished up with two close ups of new active regions in 540nm.
