SN 2004S Ia in ESO427-006 (MCG -05-16-021)
OBJECT: SN 2004S Ia in ESO427-006 (MCG -05-16-021) (Sab galaxy) which in Leda is
ESO427-006 (MCG -05-16-021) (Leda).
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.

SUSPECT Index.
SUSPECT Index: SN 2004S Ia.
There are 8 spectra which are the entire krisciunas2007 set.
There is no great picture of
Fritz Zwicky (Wikipedia).
Just say Fritz Zwicky aloud and you can tell he's an up-to-date person.
CORRECTIONS: Heliocentric velocity 2785 +/- 11 km/s (2007jul02) from
ESO427-006 (MCG -05-16-021) (Leda).
Galactic foreground 0.43/4=0.1075 reddening from
ESO427-006 (MCG -05-16-021) (Leda).
But this is derived from
Schlegel et al. (1998).
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.
