Go look at the sun right now if you can!

For those with 8/8ths Oktas......

Lots to observe in Ha.     Bits flying off at 2 o'clock position.

This is from 

Solar data view select (nso.edu)

Click on the site name for the observatory ( Cerro Tololo in this case)  and it downloads a movie of the frames.

Yes it was that bit flying off - for the 20-25 mins or so that I was watching it went from something that looked big & bold but just about tenuously attached to the disk to a wisp like thing jettisoned off into the darkness, gone forever.

Just saw animation that @Craney linked above - it really shot off like a projectile in the end!

Yes it was crazy how relatively fast that was happening - just thinking about the staggering amounts of energy that must have been in flux there and then in such a short period of time and across so much volume of space.  You always hear how solar observation can be so dynamic - that's not wrong!

It was also v interesting clocking the etalon - it really changed what could be seen.

It really was something.  Esp the scale of it a the start.  I'd been wanting to look at the sun all day and just couldn't manage to do so until that time - got lucky!

Magnetic flux is really building up now. 

I'm part way through reading Viladrich et al "Solar Astronomy" - its fascinating stuff.  I had no idea about how the temperature changes so much, and the role the magnetic flux plays (including in pushing the coronal temperatures to 1 million Kelvin!)😲
