Scientific paper

We report on the final epoch of our VLA monitoring of SN 2006gy, which is among the most luminous supernovae ever seen. On 2008 May 30.5 UT (~650 days since shock breakout), no radio emission was seen at the optical position with the following 3-sigma upper limits: 8.4 GHz: 0.45 mJy/bm; resolution ~9", 43 GHz: 0.62 mJy/bm; resolution ~1.8". (the upper limits are somewhat larger than previous ones because of the lower resolution and increased contribution from the galaxy background).
