SN 1999aw Ia in an Anonymous Galaxy


Geoffrey Chaucer with an astrolabe.

OBJ:   SN 1999aw Ia in an anonymous galaxy (faint blue dwarf galaxy) which in 
         Leda
         is ?.
         The CfA List of Supernovae
         confirms it was an anonymous galaxy once.  Maybe now it's become a somebody.
DISCOVERY:  1999mar09 UT by {strolger2002}. 
MAX:  1999mar17.2 +/- 0.3 (JD 2451254.7 +/- 0.3) in B \citet{strolger2002}.
           See the US Navy Observatory 
           Julian Date Converter.
           This day of the year 76.
SUPERNOVA of the YEAR:  M = 49.

COMMENT:   This is a shallow silicon SN Ia.

         of 19.4 days for Ia rise time in B.

       \citet{howell2004} They
       have one SN 1999aw spectrum probably from strolger2002.

HEADER: Header Common header information for this supernovae.
        The common header may (or may not) be updated relative to the header information above
        (D. J. Jeffery (2007jan01)).

REP:  F_lambda (erg/cm2/s/A) vs. lambda (ang)  (iformat = 1)
COR:  not deredshifted (heliocentric velocity 11,400 +/- 300 km/s from strolger2002 and not
         Leda
      not dereddened (Galactic foreground 0.14/4=.035 reddening from strolger2002 and not
         Leda
        but derived from
     Schlegel et al. (1998)
      not smoothed ????, not photometric ????
      Derived bolometric maximum is ??? (see above).
OBS: \citet{strolger2002}??, but
      it is relatively undocumented.   It comes from David Branch files.

Date: 1999 with 1999mar17.2 +/- 0.3 (JD 2451254.7 +/- 0.3) for B maximum gives:
