20140101 Spectrohelioscope solar events

Post by Wah »

1. Ha prom at solar limb



2. Big prom detached from the spectrum



3. Fast filament on the spectrum

After some calculation:
The blue wing is about: 194km/s approaching us
The red wing is about: 171km/s leaving us

4. He-D3 solar limb bright line, the 2 absorption lines are from element Na.



5. He-D3 big prom is very dim, the spectrum need to be far over exposed.

Human eyes have high dynamic range, I could barely see the prom and the spectrum at the same time.
Visual effect is FAR FAR BETTER than the images!!!

6. Ha merged image


7. He-D3 merged image with dim prom

Nice presentation of the filament in H-alpha spectrum.
I like the He prom as well.

Merging more than 100 lines of spectrum, I can get many solar disk images.
Stacking them into an animation, we can see blue wing and red wing features are different.
Blue wing filaments are flying away from the solar surface, bluer the faster.
Red wing filaments are falling down to the solar surface, redder the faster.

The animation is very interesting - can you put the waveband at the bottom as it changes? I have no idea what Im lookin at...

I was using Photoshop to create the animation.
Labeling every frame requires lots of work, I don't want to spend so much time on it.
Is there any fast way to do so?

I can tell each frame is about 0.188A bandwidth...
