SN 2004eo Ia in NGC 6928
OBJECT: SN 2004eo Ia in NGC 6928 (SBab galaxy) which in Leda is
NGC 6928 (Leda).
DISCOVERY: 2004sep17.5 UT by K. Itagaki (2004)
MAXIMUM: 2004sep30.7 UT (JD 2453279.2) in B (pastorello2007, p. 1533).
See the US Navy Observatory Julian Date Converter.
This day of the year 274 remembering that year 2004 was a leap year.
SUPERNOVA of the YEAR: M = 145.
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 (2007jan01)).
COMMENTS: A cool(CL) SN Ia according to David Branch, but not an extreme one (?).

SUSPECT Index: SN 2004eo Ia
There are 0 spectra.
There is a 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 4707 +/- 5 km/s (2007jul02) from
NGC 6928 (Leda).
Galactic foreground 0.47/4=0.1175 reddening from
NGC 6928 (Leda).
But this is derived from
Schlegel et al. (1998).
OBSERVATIONS: From (3).
1) SUSPECT: no spectra.
2) Eddie Baron: no spectra.
3) David Branch: has the pastorello2007 spectra in /home/branch/synow/04eo.
SPECTRUM LOG:
JD times for the SN 2004eo spectra of pastorello2007 .
Bmax from pastorello2007 where the JD Bmax is JD 2453279.2 with probably at
least 0.5 uncertainty.
The the pastorello007 spectra are not deredshifted relying on the Si II 6355 minimum in
the earliest spectrum.
Note the dates and wavelengths below rely on pastorello2007 directly.
