Prominences & Filaments | HA & CaK | Feb 9th 2020

[MalVeauX]

Heya,

Another clear day, but the seeing was poor for my area typically. Regardless it supported the image scale (0.5"/pixel) in both wavelengths with lucky imaging. Took a look at today's prominences, some faint ones, and some nice dark filaments. No real noteworthy surface features today otherwise. Earth scales provided for the prominences. Most of them are on the Eastern limb quadrants. Both chromospheres represented, the lower & upper via Ha & CaK.
