Total solar eclipse 2017

Approximately every 18 months the moon passes between the sun and earth in the same plane as the sun-earth system and a solar eclipse occurs somewhere on the face of the earth.

Like the Sun and Moon, I think the humor behind that diagram went over your head! Whoooooosh!

"Solar Plexus"? "declension"? "obsequity"?

I probably should have mentioned that I found the cartoon on the xkcd website: https://xkcd.com/1868/

Now, it's time to build my eclipse viewing box. Alas, I am stuck with 5 pairs of glasses I am afraid to use. At least Amazon is refunding my money. But trying to find a pair of approved/safe eclipse glasses in my area has become a huge chore to say the least. I think a lot of retailers have decided that the number of fakes and questionable glasses makes the legal risks not worth the few dollars of profit.

Do your glasses have the ISO-certification seal on them? If not, just do a basic safety test, like the following:

Quote:

The AAS suggests you check sunlight reflected off a mirror or a shiny metal object. If sun is behind clouds or on the other side of the earth when you want to test your glasses, you can use a bright-white LED such as the flashlight on your phone or a bare LED lightbulb. The reflected sunlight or bright, white, artificial light should appear very dim through a safe pair of eclipse glasses. If you can see light behind a lamp shade or a soft, frosted light bulb through the glasses through your eclipse glasses, then they aren't strong enough to stare safely at the sun.

Actually I would do the safety check described above even if your glasses are ISO-certified. Never hurts to be extra sure when it comes to looking directly into the sun.

Thank you!!! We have ISO-certified eclipse glasses but got the Amazon email about them. I was going to use them anyway, but this sounds like a simple, easy test to try beforehand so I plan to do it.

Anybody can slap the ISO stuff on glasses, so I wouldn't just go by that. Do the test. (though I am still scrapping the ones that Amazon refunded me for, since I managed to get new ones from a proper vendor)

Got an email today from a friend who runs the chamber of commerce in a small city in the path of totality. They have been selling eclipse glasses at the average rate of about 300 an hour for the past week. They're totally overwhelmed.

No need to use eclipse glasses if they scare you. You can make a binoculars rig like I did.

I checked the cloud cover (thanks for the link, FMN). At first, the cloud cover diagram looked sketchy (I'm glad I'm not down in the distant south east...lots of clouds there), but when I zoomed-in, I see that the prediction is completely clear for where I will be standing

Yes whooooosh! Apologies to Chuckanut! The diagram wouldn't expand for me so I couldn't actually read all of the annotations. My bad. Although I may also be one of those folks who fails to see anything humorous about astronomy. Now astrology, I can see the humor in that!

Are you sure it's 300/hr? That's over 20,000 in a week.

But if that is the case, just let me know if they are in Missouri, and where, so I can avoid that area.

No, it's just during the 8 hours a day M-F that they are open. Still a lot. They have had to make a lot of extra trips to their supplier to keep up with the demand.

And it's Kentucky, not Missouri.

A few hours until decision time for our destination, since Amtrak has a 48 hour cancellation policy. Greenville forecasts more cloud cover, but we fear the traffic if we drive to TN will be horrendous and stressful. Leaning back toward Greenville and simplified travel.

I'm glad it is Kentucky, but any way you add it up that is one boot load of glasses.

We landed in a Portland an hour and a half ago. Airport folks said the traffic was really backed up around the airport. The people behind us and the people across the isle on the plane were all heading to Madras.

[RunningBum]

We opted for the train to Greenville. Once in a lifetime traffic seemed worth avoiding even if there's more risk of clouds in Greenville.

[easysurfer]

Kinda blasphemy. But my plan is to not take any chances and watch the live eclipse broadcast on TV. I know, the like the real thing but at least in high def .

[Ronstar]

I just read online that GoPro cameras do not need a filter to film the eclipse, due to its wide field of view. Could make for an interesting video - watching the eclipse from a brewery.

Curious as to why you think traffic will be worse in TN than SC. Have you read or heard anything specific about TN that makes you think that? My plan involves driving up from Atlanta to central TN, and I'm not aware of anything that would make me want to rethink that right now. But please share if you know something that might be pertinent!

Some friends have a place over in the Prineville area - Gal was texting them yesterday morning and they were saying it was all hype - so dramatic car traffic increase at all. Yesterday afternoon they said they were hunkered down and the road past their place was loaded.

Salem is allowing campers in the city parks - sleeping bag, small tent - but note they will be turning the sprinklers on again on Monday night. Independence has sold out it's 127 10x30 patch of dirt camp sites for $275+, don't know if all motor home sites are sold out. Sounds expensive, but as much infrastructure - lights, portapots, water, activities, staffing - as they have I'll be surprised if they break even. Some Pink Floyd cover band was cranking Dark Side of the Moon last night down in the park - we got to share from our bed.

Not crazy about the traffic flow around Nashville.

Check your weather predictions again, folks!

This morning, wunderground says 20% chance of thunderstorms here on Eclipse Day! Accuweather says "Some sun, a thunderstorm, humid". Boo.

We just might get to see this eclipse (75% of totality here).
