Yesterday's Sun in Ha & 540nm 19 December 2022

Another beautiful Melbourne morning without clouds - summer at last
The seeing was not fantastic but we had a very enjoyable session taking these images.
We imaged the full disk in both Ha and 540nm.
Then there is a comparison of AR3169 in both Ha and 540nm.
Then there is a comparison of the photographic trio of active regions AR3163, AR3166 & AR3162 in both Ha and 540nm.
And then a two panel mosaic of AR3168 with associated very long filaments.
