Magnitude vs. obscuration?

Whenever eclipse geeks are talking about their calculations, they always need to make sure they are careful to distinguish as to whether they’re talking about “magnitude” or “obscuration”. In case you’d like to understand this, too, here is a quick explanation.

I’m going to use the word “percentage” below, … Read More »



I have a department-store telescope with a “solar filter” – can I use that to look at the Sun?

NO! NO! NO!

These cheap “filters” are manufactured and marketed as being able to be inserted into the eyepiece. That means that by the time they get to the filter, all the Sun’s rays have gone through … Read More »



What time will the eclipse happen for me?

This depends completely on where you are.

If you are in the path of totality, then you first see the beginning of the partial phase. (This is called “C1” by astronomers) The Moon’s “bite” out of the Sun will grow slowly, until the moment you’ve been waiting for: totality!

After the eclipse is over – then what?

It is an almost universal reaction after seeing a total eclipse: You will be asking yourself within about a half a second when the next one is. And the answer to that is that there isn’t another one on land until 2019 (in southern Argentina and Chile ONLY). After … Read More »



Can’t I just watch the eclipse on TV?

You sure can – the same way you can watch a wonderful meal being eaten on TV, a live shot of a huge pile of hundred-dollar bills on TV, or a guy having a great date with a wonderful woman – on TV. It’s not the same as being … Read More »

For those in the path:

If the sky is completely overcast, it will get … Read More »



Can I bring my pets to watch the eclipse?

NO!

Animals will be scared senseless by the eclipse, and you will want to be enjoying it instead of trying to calm your crazed critters. Everyone around you will not want to be bothered by your animals either, so please leave them at home. Again, you have to take … Read More »



I have to drive a long way to be in the path. Why should I go to all that trouble?

If you go, you will understand. It is simply the most unbelievable thing you can ever experience in your life. If you stay home, then nothing we can say will convince you that you should’ve gone. Please trust someone who’s seen twelve of these, on all continents – don’t miss … Read More »



How do you know this far in advance where the eclipse is going to be visible?

A lot of math.

No, seriously, astronomers do know the equations that model the motions of the Earth and Moon extraordinarily accurately. Eclipse predicting has been around for thousands of years, but with the computers we have now, those predictions are actually very quick and VERY accurate.

What is … Read More »



When will the eclipse happen?

Monday, August 21, 2017. Clear your calendar!

Total eclipses happen about once a year, somewhere on earth, but they’re usually in very out-of-the-way places. There are groups of die-hard eclipse chasers who think these are so beautiful, they travel to the far corners of the earth to see them. Their … Read More »
