Supernova 1999cb in mrk881 This image of Markarian 881 with Supernova 1999cb is a composite color image made from a 200s V-band and a 300s I-band exposure taken on 1999 May 14 UT. North is up, and east is to the left; the field of view is 296"x309". The blue face-on spiral galaxy is Markarian 881, and SN 1999cb is the blue stellar object 11" west and 10" south of the galaxy nucleus (to the lower right from the galaxy center). Odd Trondal made this FIRST EVER supernova discovery from Norway using his backyard telescope in Oslo. The SN was about a month past its maximum brightness when the image was taken. Click on the image to view a closeup of Markarian 881 with the supernova. The images have been smoothed with a Gaussian filter and logarithmically scaled. The CCD exposures for this color image were taken by Ragnvald Irgens and Henning Holen and the image processing was done by Håkon Dahle .
