Today's Large Prominences | Oct 15th 2019

[MalVeauX]

Heya,

It was cloudy and not nice outside this morning so I missed the window to use finer scales, but later in the afternoon the sky cleared up, but I was greeted with lousy seeing. Still, 120mm aperture at 656nm tends to work out even when my seeing is poor. So I managed to get some data on two very interesting prominences. One is a hedgerow morphology and the other is very faint and long and seems kind of like a detached fan morphology perhaps? There's a few dark little filaments that were the gorgeous prominences from before that have rounded the limb. Earth scales provided for reference.

Very best,

Nice clear morning here.

Hoping the clouds stay away so I get a chance to look at lunchtime due to work 🙁

Fingers crossed 🤞
