Since it's near full moon and smokey, something different.

One of the most interesting articles I've read recently.  Aurora in the tropics!

Of course, you needn’t worry about this in the upcoming solar cycle.  That’s because
yours truly spent himself into the poorhouse for a 100mm double-stack H-alpha
telescope. No doubt we’ll go into another Maunder-type minimum.

While the solar observers are unhappy, the deep-sky observers are excited and desperate to may hay while the sun (and it's spots) does not shine.

I'd love to see such an aurora display, but I dread the thought of having all our power transmission lines shooting out sparks here in California. : O

I recall seeing a pretty nice aurora here in San Jose one night.....  but here, this is from Rashad Al Mansour's vantage point in Fiddletown, in the Sierra foothills...

"As I watched, a large bright gray blue oval appeared in the NE. It looked as though a second moon was rising! The light dome it created was three times as large as the light dome that the city of Sacramento casts NNW. Suddenly this bright spot started to shimmer and cycle colors from blue gray to violet. It then started to narrow and elongate vertically until it formed another turquoise column, and next to it another panel of bright Crimson formed. Over the next several hours this pattern repeated itself until 270 degrees of sky, from Zenith to the horizon was filled with 10 degree wide crimson panels separated by 3 degree wide turquoise columns. Imagine that you were holding a gigantic crimson umbrella overhead, with the turquoise pillars representing the umbrella's ribs, that was the sensation one felt because the turquoise pillars seamed to all converge at zenith. And looking south, from the horizon to near Zenith a 90-degree wide section of sky was almost ink black."

More such reports are found in the once great but no more TAC observing reports, March 2001:

I first noticed it a Houge Park, during an SJAA Friday night in-town public star party.  I took off and observed from a darker area near my home in Los Gatos.  Hallucinogenic.
