Note kriciunas2007 calls it an Sc galaxy
DISCOVERY: 2004feb3.54 by Martin (2004)
MAXIMUM: Bmax 2004feb04.37 UT (8h 52m 48s) (JD 2453039.87 +/- 0.25) (krisciunas2007).
Bmax 2004feb03.92 (JD 2453039.42 +/- 0.64) (misra2005).
We adopt krisciunas2007's value.

OBSERVATIONS: From (1).
1) krisciunas on SUSPECT.
2) Eddie Baron has no SN 2004s spectra.
3) David Branch has no SN004s spectra it seems.
SPECTRUM LOG:
JD times for the SN 2004s spectra of krisciunas2007
Bmax from krisciunas2007 where the JD Bmax is JD 2453039.87 +/- 0.25.
The krisciunas2007 are not deredshifted relying on the Si II 6355 minimum in
the earliest spectrum.
Note the dates and wavelengths below rely on krisciunas2007 directly
and not on the suspect SUSPECT.
