Is there any hope of getting further spectra?
Below is the list I sent to WIYN to observe. In my opinion, the "B"
candidates on this list should be the highest-priority low-redshift
candidates for spectra. They are a combination of what we've observed
with TNG together with a probability that they are really SNe (including
T02-030, which it looks like we may have caught within days of
explosion).
----WIYN MAY 17 VERSION 1.0
Here's the list of things to observe at WIYN. This may be modified if we magically get spectra of some of the unconfirmed candidates in the next day. Candidates are listed in the order I think they ought to be done, but feel free to mix-n-match. (I've tried to put lower priority and brighter candidates into the moon-time.)
Priority key:
A -- we have a spectrum and are following B -- no spectrum yet, but highest hopes C -- we may never get a confirmation spectrum, but might get a redshift later
T -- followed with TNG d -- ltcv going down as of last information (TNG) u -- ltcv going up as of last information U -- ltcv going up hugely as of last information f -- ltcv flat or uncertain as of last information
(Lightcurve information about T02-029 and S02-058 will hopefully come in later.)
Mag is the discovery magnitude.
For all of these, "on-color" (the color of the discovery) are more important than "off-color". We'd prefer both, but getting the full exposure in "on-color" will help ensure getting a good stretch.
