Thank you, I'm glad I caught this here as it's been cloudy all day and night so far.

When else would one occur?

At night?  I never took astronomy, though.

A solar eclipse, by definition, must happen during the day. The moon passes between the sun and the earth. The moon’s shadow is cast on the earth.


A lunar eclipse, by definition, must occur at night. The earth passes between the sun and the moon. The earth’s shadow is cast onto the moon.

True. We were just on the wrong side of the planet to see it. (Unless you are in Africa, India or Central Asia.)

If you have clear skies tonight, you can get a good look at the Red Planet Mars tonight. At 12:45am CDT, Mars is in the Southern sky, about 45 degrees up from the horizon. It's the closest Mars has been to the Earth in 15 years (since 2003).

Not the crime?  Not the overcrowding?  Not the traffic and the stupid, frantic pace... But star events?  :P

I'm close enough to the edge of the city that I can get out if I want- at least for a short time.

The timing is perfect for heading out right after MITD. Just remember Northeast and with numbers like that unless you are actually in a big city you should see something.

Mysterious Signals From Space
« Reply #13 on: August 01, 2018, 09:04:59 PM »
https://www.cnet.com/news/new-radio-telescope-picks-up-mysterious-signal-from-space/

"The Canadian Hydrogen Intensity Mapping Experiment (CHIME) in British Columbia detected the first-ever FRB at frequencies below 700 MHz on July 25, a signal named FRB 180725A.

As you might guess, FRBs are milliseconds-long bursts of radio emissions that come from some unknown source across the universe. They're one of the newer cosmic mysteries around, having been first detected only about a decade ago. Possible explanations include bursts from magnetars, exploding black holes, and yes, highly advanced alien civilizations."
