Supernovae in 1994:

K-band Image March 26 08:10 UT
J-band Image March 26 08:10 UT
These images were acquired at the 1.3-m telescope at Kitt Peak using an Infrared Array . The observing conditions were poor (bad seeing) and the pixel scale of the detector is rather coarse (1.35 arcsecs per pixel). Also the nucleus of the galaxy is quite bright at these wavelengths and Supernova aren't because they are farily blue. The supernovae is barely visible in the K-band image and shows up a little better in the J-band image. The constrast between the background galaxy and the supernovae is much better at shorter wavelengths. This data shows how difficult IR measurements will be when the supernova occurs this close to the center of a galaxy.
