I don't know much about how astro-photography is done nowadays. I have heard of supercooling image sensors, especially in IR astronomy, and also they seem to have some pretty advanced software.

Interesting about Lambert and optics.

And well... Maxwell goes without saying.

The sun developed a real nice filament next to a coronal hole. Huge string of plasma, many Earths long, just sitting there in an arch. Some of it erupted and reinforced the flow from the hole. Kp briefly got to 4 (storm threshold). More gorgeous aurora is expected when the next CME gets here in a day or so. That's all.

looks like a personal Aurora, must be leaking sunshine may need to fix something or plug a hole.

What it’s like to get your aura photographed at Detroit’s Aura Aura

Aurora was pretty, but the CME missed Earth.

The filament is still there. It's amazing, and very rare. Usually they're straight, but this one is practically spiral shaped, and bigger. It just rotated off the visible disk, though.

What you're seeing is plasma around an intense magnetic field. If the field ruptures somewhere, you get an event like a mini solar flare, with mass ejection into space.

The auracam sounds like a GSR machine hooked to an expensive Polaroid camera. Its output is interesting and sometimes pretty, but I doubt it's measuring anything to do with the person's inner spirit. Real Kirilian photography requires that the object be laid on a photographic plate and charged with a huge electric source like a Tesla coil. What you're seeing is the discharge. Not the safest thing for humans to be doing.

2017 Geminid meteor shower this week

Quote:
........"With August's Perseids obscured by bright moonlight, the Geminids will be the best shower this year," said Bill Cooke with NASA's Meteoroid Environment Office. "The thin, waning crescent Moon won't spoil the show."

The shower will peak overnight Dec. 13-14 with rates around one per minute under good conditions, according to Cooke. Geminids can be seen on nights before and after the Dec. 14 peak, although they will appear less frequently.

"Geminid activity is broad," said Cooke. "Good rates will be seen between 7:30 p.m. on Dec. 13 and dawn local time the morning of Dec. 14, with the most meteors visible from midnight to 4 a.m. on Dec. 14, when the radiant is highest in the sky."..............

Active Region AR2699 emerged around the solar limb a couple of days ago, and it has grown considerably since. It's now unstable enough for M class flares, though it hasn't made any. Many C class, however. Those are the piddly ones.

It's a real nice paired sunspot group with the unstable magnetic fields and everything. Much bigger than Earth. It could swallow this planet whole, and there would be no trace. The planet would vaporize. Poof. Just like that, there's no drumpf, and no North Korea, and no Pennsylvania Avenue to have a stupid military parade on, and no military to be dragged into said parade. And no anything else either.

Cosmology is like that.

AR2699 continues to transit across the Earth facing disk. It's approaching the middle, and in a very geoeffective position. It managed a rather piddly little C-class flare this morning (US time). It shows up real nicely as a small spike in the otherwise flatlined X-ray. Apparently HF propagation took a dip on the daylight side of this planet, but not a major dip.

AR2699 is now four sunspots, and a rather impressive group. It's made some more flares, none of consequence. A C class event did send out a weak CME that may or may not combine with flow from a coronal hole to make some aurora worth showing the tourists.

Confirmed on the CME, but it's a pretty weak one. The coronal hole is probably more noteworthy, and it isn't much either. It's a very nice coronal hole in a very geoeffective position, but in solar minima that's pretty normal stuff. It's kind of the solar-terrestrial version of rain in Seattle.
