Supernova SN 2011fe in Messier 101

Here is a sketch of the unusually bright supernova that appeared last August 24th in the Pinwheel Galaxy (M 101) in Ursa Major. SN 2011fe is now at its maximum around magnitude 10 and it is very easy to see in my 120mm refractor, but it was also easy with an 80mm refractor (I estimated magnitude 10.3 on Sept. 4th and 10.0 on 6th). In contrast, as I am observing with moderate light pollution and M 101 is low, the galaxy itself is barely visible and I only can see the central region with effort. SN 2011fe is a nearby type Ia supernova and the brightest one since 1987. 2011 is being a great year for supernova observers!

  1. Diego,

    Very nicely done and informative! This is one little fellow I will not be able to catch with my 130mm Newtonian with the light pollution in the sky of Montreal!

    Thanks for sharing!

  2. Diego,

    Nicely done, just like I saw it! I had the same similar conditions and appearance of the supernova with its host galaxy M101.

    Maybe I’ll submit my sketch once my computer gets fixed at the shop.

    Dark and clear skies,

    Juanchin
