General Description

MOS observations of the hosts of two SNe candidates that have now faded
 from view and of a new
candidate that will soon be at maximum light.

Three MOS OBs (226119, 226120 and 226121) together with one standard (226116) have
 been submitted.

The standard is at 20hrs whereas the MOS target is at 22 hours. You may find it
 more convenient
to do the standard first and the MOS. The standard is LTT 7987. Since this regularly
 used for FORS2,
you can use the finding chart that is in the control room.

Critical Observing Condition Constraints

Seeing is the most important constraint.

Time-Critical Aspects

```
Target is at 12 hours and is setting.

Special Execution Requirements

Special Calibration Information

Since we'll be working at wavelengths greater than 8000 Angstroms,
removal of the strong telluric absorption feature at 9300 Angstroms 
will be important.

For this reason we have also submit OBs to observe
spectrophotometric standards with the 1" slit. These standards should
be observed after the science target has been observed.
