Ha Full Disk - 2nd July

Was pleased to wake up this morning to blue skies, so got out of bed nice and early to get some viewing in before work. Seeing wasn't great so lots of sub frames and lots of runs were key to picking out a best image. First up the full disk with the SM90 and GH3 ICX916M - again lots of people online saying the sun is blank, absolutely not! Mid disk a filament divides opposing magnetic polarities of the turbulent plage of the active regions that were with us in April. In northern polar regions we see the hints of a near limb to limb polar crown which marks the position of start of cycle 25 jetstream. Then, in the southern hemisphere S6205 is a cycle 25 feature.
