. I measured my limiting magnitude on this picture at about Mag 18.9. I also did some photometry near for the SN positon, and I found a star liked object at about Mag 17.6. I think this object is 1999br. This image is deconvoluted, but I measured the magnitude pre-deconvulution. Kereszty Zsolt . Hungary, Miskolc . Back to Bright Supernovae .

. Comment on J0334-4008 . Our image is not consistent with the one at 5 GHz by Shen et al. (1998) which shows an extension in the opposite direction to that seen in our image. A redshift of 1.445 is widely quoted for this source, but there is little to support this value. Drinkwater et al. (1997) were unable to measure a redshift for this source. VLBApls home page .
