Solar Tadpole-Like Jets Seen With NASA’S IRIS Add New Clue to Age-Old Mystery

Keep an eye out for tadpoles! Scientists have discovered tadpole-shaped jets coming out of regions with intense magnetic fields on the Sun. Unlike those living on Earth, these “tadpoles” — formally called pseudo-shocks — are made entirely of plasma, the electrically conducting material made of charg...

Filament and Prom from Feb 17

We're just getting a few hours of Sun between rainstorms here in California. I captured the filament and a very dim prominence in the morning before the showers came in.

Couple of Nice Proms Nov 27

I wasn't sure it was worth it to set up for these dim proms at first, but with some exposure tweaking they looked pretty nice.

I woke up this morning planning to take some shots of the active region on the solar limn, but when I looked out at my canvas-covered scope there was a Cooper's Hawk using it as a perch. The sky is cloudy so he got to keep his perch for now. CoopersHawkTelescopePerch_DSCN4679.jpg CoopersHawkTelescop...

Well it is nice to see something happening on the Sun to photograph today! The little AR has three spots and a couple of interesting small proms. Here's what I got:

Wednesday's Proms And Disk

These proms were large but faint so I had to crank up the gain and exposure to get them to show decently.

Re: ISS pass 19th October 2018

Great catch! That's pretty rare.

Catching the transit in H-a would be awesome, but the exposures are longer and the motion might blur.
