AR2806, AR2807, Prominences | HA, CaK | March 5th 2021

Recommended Posts


Had another clear morning with fair seeing. Seeing was around 1.2 arc-seconds to 1.5 arc-seconds for most of this, it barely supported the 120mm aperture, but I wanted to get moderate-high resolution captures of the two AR's while they were still around and active before going back to work. There's a rather large prominence off the limb near AR2806 and the opposite limb has a great eruptive surge prominence region that was pretty active all morning that is rounding the Eastern limb. Might be interesting soon.

PST etalon + double stacked 1.7A 8mm blocking filter tilted in a Skybender (thanks Apollo!) and 6A 5mm blocking filter.






















Time Lapse Animations:

There's a surge prom on the limb erupting. This is 4.5 minutes of real time it changed so fast.
This animation is now on the front page of SpaceWeather for 3/5, woo!
