Large Prom, Filaments & AR | HA & CaK | Feb 7th 2020

[MalVeauX]

Heya,

Lots of wind in Florida right now, seeing was ok, but the wind kept things difficult. There's a large prominence on the Eastern limb that was much larger a few hours ago and has diminished today significantly. There's a little active region with what appears to bye cycle 25 polarity near the Eastern limb and some large filaments hovering near by. I was able to gather some data on that large prominence, since it was so bright, in CaK even and found it had more structure in CaK than in HA at nearly the same time frame.

B&W:
