Weird tendril-like features in chromosphere? Identification help?

Post by MalVeauX » Tue May 21, 2019 10:08 pm

Hey all,

Bald disc today, not even a prom!

But, there's always something to see in hydrogen alpha.

I'm curious what these strange tendril like structures are in the chromosphere. I find them sometimes and they are very short lived and move along. Makes me think they are related to spicules with how they come and go so quickly. But, I'm not certain what the structure(s) are/is. Maybe someone else can help identify what they truly represent?

Here's an animation to help discern the features I'm talking about from the rest of the chromospheric features.

Spicule plasma flow I guess, almost like mini arch filaments. The spicules rise and fall in 5-10 minutes or so. I am guessing if you were slightly off band in blue or red wing you would see plasma moving towards you or away from you, so you are getting direction of flow. Only guessing.
