Description

Object/Date:

SN 2019ehk @ May 5,2019 00:37 UT

Description:

On 29 April 2019 Jaroslaw Grzegorzek, a polish amateur astronomer, discovered a supernova into galaxy Messier 100 when this had a brightness at magnitude of 16.5. Five days after I took this image centered in this magnitude 9.5 spiral galaxy at 55 million light-years in constellation Coma Berenices and discoverd by Pierre Méchain on 178. The supernova is located relative near of core galaxy, 15 arcminutes toward Northeast, and its spectrum indicates that its brightness is being fairly reduced because dust clouds of galaxy.

Acquisition details:

Telescope GSO 8" N f/3.8.

Camera Atik 383L+.

Exposure 2.7 hr. (L=29x240 bin1 + RGB=8x120 bin2)

From Hoya Redonda, Valencia (Spain).
