SN 2006X in Messier 100

Comparison between two images of Messier 100, taken in March 2002 with the VIMOS instrument on Melipal (VLT) and in February 2006 with FORS1 on Kueyen (VLT). The difference in colours comes from the different filters used. The supernova SN 2006X is clearly present in the FORS1 image as the bright object in the middle, just above the lower main spiral arm. It is not seen in the VIMOS image.
