Eclipse Intersection - All this
I’ve been planning my solar eclipse trip for next month, working out where I want to view it and a couple of backup locations if my first choice has bad weather. Because I can drive down to southern Illinois (or Indiana or Kentucky) the morning of the eclipse, I don’t have to worry about getting a hotel—and a good thing, because it’s way too late for that.

I’ve played with a few interactive eclipse maps, and for my money the easiest to use is this one from NASA. It’s based on Google Maps, so you can zoom in and switch between map and aerial views using familiar tools. Clicking a spot on the map brings up a nice popup with all the time and directional information you’re likely to need.

APOD: 2017 July 16 - Lightning Eclipse from the Planet of the Goats
Explanation: Thunderstorms almost spoiled this view of the spectacular 2011 June 15 total lunar eclipse. Instead, storm clouds parted for 10 minutes during the total eclipse phase and lightning bolts contributed to the dramatic sky. Captured with a 30-second exposure the scene also inspired one of the more memorable titles (thanks to the astrophotographer) in APOD's now 22-year history. Of course, the lightning reference clearly makes sense, and the shadow play of the dark lunar eclipse was widely viewed across planet Earth in Europe, Africa, Asia, and Australia. The picture itself, however, was shot from the Greek island of Ikaria at Pezi. That area is known as "the planet of the goats" because of the rough terrain and strange looking rocks.

How to safely enjoy the 2017 solar eclipse, a buyer’s guide for normal people
On August 21, 2017 across the entire United States, the Moon will move in front of the Sun, partially blocking it from our view. For those on the path of totality, the Moon will entirely block out the Sun for more than 2 minutes. I’ve been looking forward to seeing a total solar eclipse since I was a little kid, so I’ve been doing a lot of research on what to buy to enjoy the eclipse safely. Here’s what I’ve come up with

A solar eclipse could wipe out 9,000 megawatts of power supplies • Bloomberg
Naureen Malik:
<p>This rare event, during which the moon will completely obscure the sun, will cast a shadow along a 70-mile-wide (113-kilometer) corridor stretching from Oregon to South Carolina on Aug. 21. Based on a Bloomberg calculation of grid forecasts, more than 9,000 megawatts of solar power may go down. That’s the equivalent of about nine nuclear reactors.

The impact is a testament to the ninefold increase in solar installed in the U.S. since 2012 and highlights the risks associated with relying on an intermittent resource such as the sun for power. The onslaught of wind and solar resources is already regularly contributing to wild swings in power supplies across grids, sending wholesale electricity prices below zero on some days.

On Thursday, PJM Interconnection LLC, operator of the nation’s largest power grid covering parts of the eastern U.S., estimated the eclipse could take out as much as 2,500 megawatts of solar generation on its system from about 1:30 p.m. to 3:40 p.m. North Carolina and New Jersey may bear the brunt because so many panels are installed in those states. PJM said rooftop solar panels will account for 80 percent of the anticipated outages.</p>


I've heard that the earth completely obscures the sun for many hours a day, too, yet power supplies have generally managed to cope. This is a great attempt to connect the solar eclipse with solar power. It's also desperate.
