2 - 3 Spectrophotometric standards with wide slit
One telluric standard with narrow (high s/n) slit.
30s B/V exposures are ok for direct images of all the targets.
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.
