happy solstice

more solar work

first a prominence animation.  

I've increased the imaging frequency and animation speed to give more fluid motion in this one.  


here's the prominence image now that i've typed enough to avoid the annoying navigation bar to the upper right (animation link below)








Here's the animation (large file)

the animation is a total of 76 images taken every 2 minutes
starting 3:30 pm on 5/31/14
each image was constructed by stacking 300 frames 
captured at 11 frames per second

here's a crop off the lower left side edge with rapid, small scale eruptions:




this is full scale with a rate 5 fps (half the prior image)
(top is 75%) 


Here's a full disk animation which is...less dramatic
the interesting part is that you can see the sun's slow rotation
as the animation snaps back to the beginning:
