Question Northern Lights viewable in Iowa

I think I saw aurora borealis in Iowa several years ago.


Does anyone know if and when it will be visible in Iowa this winter?

The moon was beautiful tonight. I am sure if you all have snow the reflection was beautifull too. Sadly, this farfromhome gal has seen nearly 70 degree days for 3 days straight. It does not feel like a home town Christmas!!

The moon was fantastic last night! If you all have snow, I am sure that the moon's reflection was beautiful too! This farfromhome gal has had 3 days of nearly 70 degrees. Not the hometown Christmas I was hoping for! Farfromhome's daughter has been wishing for snow. May have to make a Winter Visit!

Resident astronomer here...

Aurora are fairly rare in Iowa because we are so far south (although it hasn't felt that way this week). I watch the sky a lot, and sometimes go for a year or two without seeing them. They can occur any time of year. They are fairly unpredictable, and can occur with almost no notice. You can sign up for email alerts at www.spaceweather.com.

The source of these is related to sunspot activity on the sun. Sunspot activity goes in an 11 year cycle, and right now we are at the minimum phase of the cycle, so aurora are even rarer right now. Sunspot activity should be on the increase over the next few years, so hopefully we will see more aurora too.

There is a time-lapse movie I made two years ago linked in this thread:

The above link was for 2008's biggest full moon.

This link is for the
Biggest Full Moon of 2009

If skies are clear Saturday, go out at sunset and look for the giant moon rising in the east. It will be the biggest and brightest one of 2009, sure to wow even seasoned observers.

I can't wait to see it. Hopefully it will be clear outside tonight.

It's incredibly bright too!

It's going to be a nice night to be outside with the moon shine reflecting on the freshly fallen snow.
