SN 2002er Ia in UGC 10743
OBJECT: SN 2002er Ia in UGC 10743 (Sa galaxy) which in Leda is
UGC 10743 (Leda).
DISCOVERY: 2002aug23.2 UT by Wood-Vasey et al.
MAXIMUM: 2002sep07.2 (4h 48m) (MJD 52524.2 +/- 0.5) in B (pignata2004).
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 one has JD 2452524.7 for Bmax.
See the US Navy Observatory Julian Date Converter.
This day of the year 249.
SUPERNOVA of the YEAR: M = 148.

For SN 2002er, this has 0 spectra and 0 photometry.

There are 5 spectra. Probably only the 2002sep07 spectrum is a useful complement to the kotak2005 spectra.

SUSPECT Index: SN 2002er Ia.
There are 25 spectra all from kotak2005, but there is the 26th kotak2005 spectrum?
The missing one seems to be the 2002sep24 spectrum: it's an IR spectrum.
But 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 2570 +/- 13 km/s (2007jul01) from
UGC 10743 (Leda).
Galactic foreground 0.69/4=.1725 reddening from
UGC 10743 (Leda).
But this is derived from
Schlegel et al. (1998)
OBSERVATIONS: From
1) SUSPECT: All from kotak2005
2) Eddie Baron: has all the christensen2003 spectra.
2) David Branch: only has the kotak2005 spectra and so is redundant with SUSPECT.
SPECTRUM LOG:
MJD times for the SN 2002er spectra of kotak2005
Bmax from pignata2004 where the MJD Bmax is MJD 52524.2 +/- 0.5.
As far as I know, all the kotak2005 spectra from SUSPECT
are in the observer frame.
These dates are only for a subset of the kotak2005 spectra on SUSPECT.
