Today's Crazy Prom Forest! Plus Active Regions in HA & CaK | Sept 13th 2018

Heya,

This morning looked clear for a moment, but the clouds were rolling in by 9:30am! Had to quickly get data, so I imaged at lower scales. The active regions are pretty calm, no visible umbra on anything. But the prom forest on the limb is amazing! Totally crazy, thick, and covering a huge chuck on the limb. Rarely see such activity during the minimum, so this was a wonderful treat to wake up to. The grouping from yesterday has simply gotten even more wild and more proms than yesterday. Really great view if anyone is wondering if they should set up today, that prom group alone is worth setting up just to look at!

The prominence forest is over 30 Earth diameters in distance around the limb.

Celestron 150mm F8 Refractor + Quark + 0.5x Focal Reducer + ASI174MM (HA)

Thanks all, :bow

+++++++++++++++++++++++

I grabbed some more data later in the evening at large scale, but the seeing was too poor and turned out poorly, but still shows the progression of the prom forest several hours later.
