August 16, 2007: As published in CBET 1034 by D. Madison and W. Li, Supernova 2007gr was discovered at magnitude 13.8 by KAIT on August 15.53 UT, and is currently at magnitude 13.5 on August 16.47. It is located in the bright spiral galaxy NGC 1058, approximately 30 arcseconds northwest of the nucleus.
August 19, 2007: Data for SN 2007gr can now be submitted to the AAVSO using the following Harvard Designation and/or name: 0237+36B SN 2007GR
Latest report from Martin Nicholson is that the SN is at V=12.83 and continuing to rise. The two prior SNe in NGC 1058 both reached a peak brightness about this level, so SN 2007gr may not get much brighter.
