Impressive prominences on the sun today 22 August 2022
The forecast was for quite a deal of rain today so when we woke to some sunshine, we set up to image only to get a couple of seconds of video when threatening clouds forced a hurried pack up. It was very surprising when by lunchtime the sky had totally cleared again. So on a second attempt we captured these images. We were particularly happy because we had been tracking a large quiescent filament to the west of AR3081 over the last few days. Today it had finally reached the limb to become a very large and impressive prominence. Coupled with a second large prom slightly to the north, they put on quite a show!
We have added an Earth to the image to give scale.
