More eclipse questions answered

I'm constantly running into people who are planning a trip to the path of totality on Monday (the 21st) to see something that hasn't happened since 1979 (in the US). The last coast-to-coast solar eclipse was back in 1918.


Forecast update:
We are still anticipating clouds to be a factor Monday, but we might get lucky in the fact that the clouds we DO have will be see through. I don't think we will have to worry about rain, and if we have low clouds around in the morning, they should part in time for the start of the partial eclipse.


What will the weather do during the eclipse?
This is a great question and honestly, I've never been through one OR studied conditions during a total eclipse. However, given that the sun is covered (even if just briefly), we should note a drop in temperatures. By how much is something we will try and measure Monday in Nebraska. I think it will go down 10-15°, but by the time the temperature begins dropping, totality will likely be ending. The wind is also supposed to pick up a bit, but we are already forecasting some gusty winds, so we may not notice much change.

Viewing the eclipse safely:
As you are already aware of -
  • don't look directly at the sun unless you have the special glasses or a welding helmet that's approved for such thing. Even just the quickest glance can cause permanent damage. 
  • It is safe to look at the sun during totality (anything less than 100% it is not safe), but remember, that only lasts for a few minutes. 
  • If you have binoculars, you can look at the sun when it's fully covered. You should be able to see some interesting parts of the sun's corona, which is what you'll see surrounding the edge of the moon as it covers the sun. 
  • You can also take a colander and let the light shine through the tiny holes, and look for the crescent suns shining on a piece of paper.
Many of you have been asking about glasses to watch the eclipse. Most places that have been selling them are OUT! Yes... it's a popular event and I think finding glasses this close to the event will be difficult, but keep your eyes open.
