SN 2002bo Ia in NGC 3190


Geoffrey Chaucer with an astrolabe.

OBJECT:  SN 2002bo Ia in NGC 3190 (Sa galaxy) which in Leda is 
       NGC 3190 (Leda).  
DISCOVERY:  2002mar9.08 UT by Cacella & Hirose 
MAXIMUM:  2002mar23.0 (MJD 52356.0) in B benetti2004.
          The Asiago Catalog gives 2002mar24 which is
          the value adopted by SUSPECT, but
          that's not very precise and who's to know which is better.  benetti2004's value
          is the published one and that's the paper reference for SN 2002bo.
          Note that Modified Julian Date (MJD) is given by 
 
                         MJD=JD-2400000.5  (Julian Date).

          For some three centuries following 1858nov17.00 UT, the Julian day lies between 2400000 and 2500000.
          The MJD drops those first "24" digits and gets rid of that annoying half day thing. 

          So Bmax as on JD 2452356.5. 
          See the US Navy Observatory 
          Julian Date Converter.
          This day of the year 81.
SUPERNOVA of the YEAR:  M = 67.

HEADER:  Header Common header information for this supernovae.
         The common header may (or may not) be updated relative to the header information here 
         (D. J. Jeffery (2006jan01)).

COMMENT:  SN2002bo is broad line (BL) SN Ia.

          The Asiago catalog gives 2002mar24 for Bmax (it seems).  But benetti2004
          gives the above date.  For consistency, I'll trust the dates of the paper.

SPECTRUM LOG:

     MJD times for the SN 2002bo spectra of benetti2004
     Bmax from benetti2004 where the MJD Bmax is MJD 52356.0
     but the error is probably at least .5 days.

     As  far as I know all the benetti2004 spectra from SUSPECT
     are in the observer frame.

       There are 22 spectra all from benetti2004.  Probably some are averages or composites of benetti2004's spectra.
       But there is no a great picture of
       Fritz Zwicky (Wikipedia).
       Just say Fritz Zwicky aloud and you can tell he's an up-to-date person.
