October 23rd partial solar eclipse

Oct. 23, 2014 partial solar eclipse at maximum eclipse, as seen from Madison, Wisconsin. Illustration courtesty of timeanddate.com.

We lucked out with clear skies in Madison for the total lunar eclipse last week. Hopefully our luck will hold for the partial solar eclipse next week.

Shortly before sunset next Thursday, viewers in western and northern North America will see nearly half of the sun eclipsed by the moon at maximum eclipse. Here in Madison, we’ll see less than half the sun eclipsed, but the eclipse will be greater in the Northwest United States and British Columbia.

In Madison, the timing looks like this:

  • 4:33 p.m. – partial solar eclipse begins
  • 5:41 – maximum eclipse (nearly half the sun eclipsed by the moon)
  • 6:01 – sunset

Oct. 8, 2014 Lunar Eclipse

April 15, 2014 lunar eclipse over Madison, seen from Maple Bluff.

April 15, 2014 lunar eclipse over Madison, seen from Maple Bluff. More photos.

Update (Oct. 8): I snapped some pictures of this morning’s lunar eclipse. You can see them in my Flickr gallery.

Original post: I’m looking forward to our second total lunar eclipse of the year tomorrow morning (Oct. 8). Fortunately, the forecast for Madison calls for clear skies, so we’ll hopefully have a great view of the eclipse.

Here in Madison, timing for the eclipse looks like this:

  • 4:14 a.m. – Lunar eclipse begins (partial eclipse)
  • 5:24 – Total lunar eclipse begins
  • 5:54 – Maximum lunar eclipse
  • 6:24 – Total lunar eclipse ends (partial eclipse)
  • 6:33 – Dawn (civil twilight)
  • 7:03 – Sunrise
  • 7:08 – Moonset

In Madison, the moon will sink lower and lower in the western sky during the eclipse, so you’ll want to find a spot with a good view of the western horizon for the best view of the eclipse.

The sky’s awake, so I’m awake!

October 2, 2013 aurora, seen from Dodgeville, Wisconsin.

October 2, 2013 aurora, seen from Dodgeville, Wisconsin.

Since moving to Wisconsin several years ago, I’ve been on a mission to try to see the Northern Lights. I’ve had some success — last fall, I finally saw it and snapped some pictures — but more often than not, either clouds obscure the view, the show doesn’t make it this far south, or I’m too early/late getting out to see it. Space weather seems even more fickle than the clouds and rain we usually think of as ‘weather.’

Along the way on my quest to see the Northern Lights, I’ve found some great online resources:

  • NOAA’s Space Weather Prediction Center
    • SWPC’s front page provides a good quick look at current conditions, including the current storm level. During the geomagnetic storms that give  us the Northern Lights, SWPC staff often post updates at the top of the page.
    • An example of SWPC's Ovation Auroral Forecast

      OVATION Auroral Forecast – SWPC’s OVATION forecast is more of a ‘nowcast’ — the map shows you where the aurora is now. The map’s ‘view line’ shows where the aurora may be visible, but can be a little conservative. There have been times where the ‘view line’ is in southern Ontario, but pictures pour in from the midwest. So, even if you are south of the line, the aurora may still be visible — go take a look!

    • NOAA Space Weather scales — So, NOAA says there’s currently a G3 level geomagnetic storm in progress, with the possibility of a G3 level storm tonight. But what’s a G2 or G3 level storm mean? NOAA’s Space Weather Scales lay it out, with examples of how far south the aurora may be visible. For example, in a G2 level storm, aurora may be visible as far south as New York & Idaho (and Wisconsin!). With a G3 storm, it’s visible even further south.
    • SWPC Product Subscription Service — You can sign up to receive email alerts of geomagnetic storms from SWPC. There are many different alert types that you can ‘subscribe’ to, but some particularly useful ones are the WATCH and WARNING alerts for G2 or greater geomagnetic storms. The SWPC email alerts have given me a heads-up of geomagnetic storming and allowed me to see (and photograph) the northern lights.
  • SpaceWeather.com — This is a great place to go for space weather news. The site also features a photo gallery full of the latest beautiful aurora pictures from users around the world. SpaceWeather.com also offers an alert service that you can subscribe to (for a fee) to receive aurora alerts.
  • SpaceWeatherLive.com
  • Twitter is another great resource for aurora news. Some of my favorite Twitter feeds for Aurora news:

Good luck on your own aurora quest!
