11/19/2013 – Ephemeris – Comet ISON suddenly brightens

November 18, 2013

Ephemeris for Tuesday, November 19th. The sun will rise at 7:44. It’ll be up for 9 hours and 26 minutes, setting at 5:10. The moon, 2 days past full, will rise at 7:00 this evening

Comet ISON is full of surprises. First, earlier this year, it didn’t brighten at all as it fell toward the sun, Then in August it resumed brightening, but more slowly than predicted. Suddenly between Wednesday and Thursday mornings last week Comet ISON had an outburst and brightened 10 fold.  As of this last weekend it had continued to hold its new brightness.  It’s too close to the direction of the sun for Hubble to look at, but earthbound amateur and professional astronomers are photographing the comet in beautiful detail. On the Internet go to spaceweather.com or Universe Today for the latest images of Comet ISON. Now the comet is below left of the bright star Spica in the east southeast in the morning twilight.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.

Addendum

Here’s an image linked from November 18th SpaceWeather.com from Michael Jäger of Ebenwaldhöhe, Austria taken on the 17th.  The tail is 7 degrees long.  Check out spaceweather.com for more images in the Comet ISON Gallery.
