  SN1993J

• Type IIb (NED:1995AJ....110..880J)
  

  In M81=NGC3031 Explosion ~ Mar 23 1993 
  We were too early by 9 days to see peak in our March Run.  
  IAUCs suggest max V @3/31V=10.3(but no color corrections). 
  UN-OFFICIAL Photometry  - 3/31.2 K=10.6 +/- 0.3
  Location: 45"W + 160"S of Nucleus
  NOTE: K Mag confirmed in IAUC 5737 by Lester@McDonald Obs. 
  Note: IAUC5741 3/32 K=10.41 CNR TIRGO Observatory.
  

  SN1993G

• Type II (NED: 1995AJ....110..880J)
• NED LISTS NO IR DATA in IAU's. The Forgotten SN - We didn't detect it, but should have. Underluminous in IR?

  SN1992bu

  - FIRST INVISIBLE SN DETECED IN IR-
  Detected by Van Buren et al.
  Van Buren et al. 1994, IAUC 5960

  Processing and Analysis Center, California Institute of Technology            
  and Jet Propulsion Laboratory; and M. Shure and C. Kaminski, NASA             
  Infrared Telescope Facility, Institute for Astronomy, University of           
  Hawaii, report their discovery of an apparent supernova in NGC 3690           
  (= Markarian 171) at R.A. = 11h25m42s.0, Decl. = +58o50'10" (equinox          
  1950.0) on archival images taken in the K (2.2-micron) band as part           
  of a search for supernovae in starburst galaxies.  Offsets from Core          
  B1 (cf. Wynn-Williams et al. 1991, Ap.J. 377, 426) of the galaxy are          
  5" east and 3" south.  The object appears in ProtoCam data (obtained          
  at the IRTF, Mauna Kea) for 1992 Mar. 9 UT (when K = 16.6 +/- 0.2),           
  Apr. 10 (17.2 +/- 0.3), and May 6 (18.1 +/- 0.5).  It does not                
  appear to limiting magnitude K about 19 in NSFCam IRTF images from
  1993 Dec 27.
