General Description

The aim is to obtain an H-band spectrum of SN 2006E.
Note that the OBs are to be executed consecutively (please see waiver request)

The target is faint, hence the need to offset from a nearby source.
However, the number of detector integrations for the acquisition image have also
 
been increased so that the target itself may be visible (after background subtraction).

The strategy is to change the nod-throw between successive ~1hr OBs
which should mitigate the effect of zero jitterbox width.

Offsets from reference star for SN 2006E (see also finding chart):
5".85 W and 33".37 S
Offsets are given in the Acq-move-to-slit template -- please check sign.

Slit orientation: N-S

Waiver Requests

Waiver Request 078.D-0573A.01 was submitted and granted.

Request: consecutive execution of OBs
Justification: 
The target is a transient object (supernova) that is fading. We require a ~3hr integration
to obtain the S/N necessary to meet our science goals. 3 OBs, each of  <=1hr,
 will be
submitted; the spectra thus obtained will be combined, before commencing any analysis.
They therefore need to be obtained at the same epoch.
The observations have been requested for Jan. 2007, but the target is accessible
until Jul. 2007, so there exists the risk that the OBs might be separately executed
 at any
time between Jan-Jul. In this case, the individual spectra will  have too low a
 S/N to be useful,
and being of different epochs, they cannot be combined. Our science goals would
 thus be
compromised.
