The Type IIP Supernovae 2008ij (CBET #1626,#1627), in the galaxy NGC 6643, has been the subject of VLA searches on 2009 Jan 27.4 (UT) (ATEL #1915) and 2009 January 29.5. The second VLA search was conducted at 1.425 GHz. No radio emission was detected at the supernova location with a 3-sigma upper limit of 0.18 mJy and a resolution of 4.9". Swift X-ray observations indicate that X-ray flux from SN 2008ij is relatively weak and is declining (ATEL #1918). Based on the X-ray and radio observations to date, no further radio searches for SN 2008ij are currently planned.
We would like to extend our thanks to the VLA scheduling officers and telescope operators for their support of our observing program. The NRAO is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
