Supernovae in 1995:

• Type IC in NGC 908 Jan. 95 Image from CTIO courtesy of Bob Schommer.
• Supernovae in z=0.478 galaxy!

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.

The Rise of Supernova 1994I

Supernova 1994 I occurred in the well studied galaxy M51 on March 31, 1994. The discovery image comes from the Atlanta Astronomy Club. This image was assembled by Bill Keel . 1994I was originally thought to be a type II supernova (young massive star) but later spectroscopy reveals it to be a type I (subcategory c). The supernove has occured near the nucleus of the galaxy. The red box in the high resolution image of M51 shows in what region of the galaxy the Supernova will occur. A short exposure I-band image of M51 , taken at the Leuschner Observatory, clearly shows this new supernova. A preliminary light curve in the Visual band can be found here .

Supernova 1994Y

This occurred in NGC 5371 which is no longer visible in the nighttime sky. This image although rather poor, does show the supernova.

Older Supernovae:

SN 1993 J Light Curve

This shows the decline in brightness of a Supernova which has been monitored for about one year. The gap in the data occurs during that time of year when the host galaxy was above the horizon only in the daytime. Five optical bands are shown. The more rapid decline in intensity at the bluest wavelengths (U and B) indicate the gradual evolution of the SN atmosphere toward a cooler (redder) configuration. The best data comes from the I-band observations.
