SN 2009ap 3x500 1 17:26:43.23 -59:55:57.9 Needs classification
Galaxies that need redshift
None
2 - 3 Spectrophotometric standards with wide slit
One telluric standard with narrow slit (high s/n).
------------------------------------------------------------------------------------------------
Note: For ACTIVE SNe we should orient the slit along the paralactic angle. However,
if the SN is located close to the host it might be necessary to pick a different
and more convenient angle to avoid contamination of the host. If so, it would
be convenient to observe the SN at a low airmass. The finding charts can be
found HERE and/or HERE.
