Spiral galaxy NGC 7424 and SN2001ig
These are colour composites based on FORS 2 and VIMOS images taken in the R-band (15 sec), V (60 sec) and B (90 sec).
Two composite colour-coded image of a part of NGC 7424. The left image was made from an exposure taken with the FORS 2 instrument on VLT Yepun on June 16, 2002. In this, the supernova - although considerably fainter than when it was discovered six months earlier - is still well visible in the middle right of the image. The right image was obtained in October 2004, the supernova is no more apparent. The image covers 3.8 x 3.2 square arcminutes. North is up and East is to the right.
The images were obtained by Massimo Turatto for a large consortium of astronomers ("The Padova Supernova Group").
