Supernova SN 2006gr in UGC 12071.
 

Estimated mag. 16.6 red. USNO B1.0 magnitudes used in all these images.
Single 90sec exposure.

Supernova SN 2006dk in NGC 4161.
 

This one was at magnitude 17.0 when discovered (6/25/06). My estimate is m16.5 red. USNO B1.0 magnitudes used in all these images.
Single 90sec exposure.

Supernova SN 2006cz in MCG-01-38-2.
 

This one was at magnitude 18.6 when discovered (6/14/06). So I didn't expect to see it. There's a trace of it in this image, but not enough to call it a real detection. Stars down to R1Mag about 17.5 were fanitly detected.
Single 90sec exposure.

Supernova SN 2006cy in anonymous galaxy
 

This one was at magnitude 16.3 when discovered (6/9/06), and seems slightly brighter in this image. Reference star A is R1Mag=15.8, R2Mag=16.8. Other stars in the field have a similar spread of magnitudes, so no good comparison stars found.
Single 90sec exposure.

The 2006 supernova SN 2006ca in UGC 11214
 

This one was at magnitude 16.4 when discovered (5/4/06), and is slightly fainter now.
Single 90sec exposure - not good seeing that night.

The 2006 supernova SN 2006bu in anon. galaxy
 

This one was at magnitude 18.1 when discovered (4/27/06), and was not detected in my image. Wasn't really expecting to see it, but it was worth a shot.
Single 90sec exposure - not good seeing that night.

The 2006 supernova SN 2006cp in UGC 7357
 

This one was at magnitude 17.8 when discovered (5/28/06), and is considerably brighter now. My estimate is 16.0.
Single 120sec exposure - not good seeing that night.

The 2006 supernova (SN 2006co) in a faint ESO galaxy
 

This one was at magnitude 15.9 when discovered, now estimated at 16.0.
Single 90sec exposure.

The 2006 supernova (SN 2006ck) in UGC 8238
 

This one was at magnitude 17.5 when discovered, now estimated at 18.3.
Single 90sec exposure.

The 2006 supernova (SN 2006bs) in a faint MCG galaxy
 

This one is at the limit of detection - was magnitude 17.5 when discovered, probably fainter now, and it's just barely visible to the left of the galaxy in this image. This should probably be considered a non-detection, really.
Single 90sec exposure.

The 2006 supernova (SN 2006bp) in NGC 3953
 

Now estimated at red magnitude 14.9. Full photo history of this object here.
Single 60sec exposure.
