Hey all,

AR2786 is still kicking up some great dust, well, plasma! Lots of surge prominences going on and some minor flaring, and some new proms have developed around the eastern limb. AR2785 is still towing it along and making a great pair. You can see AR2786's companion pore trailing it ever so slightly in the photosphere, looks like a neat dipole. Seeing was average to poor, was around 1.1 to 1.6 arc-seconds all morning unfortunately, so stayed in the 120mm aperture range. Wasn't able to get calcium at this scale in this seeing conditions unfortunately, had to stay in the red ranges. AR2786 has some gnarly plasma fingers going into it's nice big spot with a great big penumbra.
