I was another beautifully clear day today. I thought that I would experiment with new ways of presenting the sun that might require less work that my prior posts. Below are the two views of the solar disk – highlighting the non-sunspot features and then the other presenting the sunspot Active Regions.
In the first image above, there are prominences including some very long jets around much of the solar edge; however, they are too faint to be readily appreciated. So, I have processed the same image in a way that brightens the prominences at the expense of destroying the detail on the disk face itself. See the reprocessed image below.
Below, I’ve highlighted the sunspot activity.
Near the eastern limb (left edge) is group AR3839 that has been producing many flares. Above it is the tiny spot AR3838. About mid-disk is AR3836 with AR3835 to the right and lower. AR3834 lies to the west (right) of AR3835, and AR3837 lies further west. The groups nearer the western limb are now disappearing to the far side of the sun.
It sure would be nice to have an EASY way to annotate these pictures. Any recommendations regarding freeware for this purpose would be greatly appreciated.
