So far, it has been an unseasonably warm winter in Central Texas. Today, it was 86 F and clear. Below is the H-alpha view of the solar disk.
Sunspot groups AR3927 and AR3928 have disappeared from view as they went around the western limb to the sun’s far side. Active Regions 3936 and 3932, seen in the sunspot image below, produced X-intensity solar flares (the strongest kind) today and promise to light up the night skies in the northern latitudes – particularly Iceland and Nordic countries (see the dynamic aurora forecast map here.) Group AR3940 has disappeared and new groups, not yet having formal NASA designations, are forming close to the eastern solar limb.
The cameos of the eastern and western limb prominences are shown in the panel below. Note the wispy jet of sun stuff (in the middle of the first image) being ejected into the solar corona.
And here is a cameo of AR3914, AR3939, AR3938, AR3937, and AR3935.
