In the galaxy NGC 1365 emerge bright blue supernova

Very bright supernova lit galaxy NGC 1365, also known as the Great Barred Spiral Galaxy, visible to observers from the Southern Hemisphere. This elegant galaxy lies at a distance of approximately 56 million light-years away in the constellation Fornax. SNe Ia, in question, was opened by Alain Klotz with the telescope of TAROT La Silla Observatory, Chile, October 27, 2012

Supernova 2012fr a vivid, deep blue star, located directly under the center of the galaxy. The author of this picture, Rolf Olsen Bullock, said November 10, 2012, this supernova was close to its maximum brightness, reaching a magnitude in the color bar R, equal to 11.90.

"To get an idea of how bright it is the event, we can calculate the absolute magnitude of the supernova M, using the following formula, where m is the apparent magnitude, and D - the distance in parsecs: M = m - 5 (lg (D) -1) », - says Olsen.
