Estimated Total Execution Time (hours, including overheads)
General Description
We request imaging ans spectroscopic (gr 3) observations of RZ Sgr and
its reflection(?) nebula. Two epochs are requested, a few weeks to a few months
apart (the precise spacing is not critical). Each epoch contains one imaging OB
and one spectroscopic OB.
Imaging: BVRI-Ha 300-sec images of the field. The star itself (V=8.4, but red) should
be placed
in the gap between the CCDs.
Spectra: Grism 3, with East-West slit (i.e. EMMI rotated by 90 degrees) with the
star now centred on the slit. 3 5-sec exposures to get a spectrum of the star (please
check for saturation) followed by 3 300-sex exposures to get a spectrum of the nebula.
We are looking for evidence that the nebula is reflecting light from the star, in
which case we will start looking for a light-echo distance. Images and spectra are
to compare star to nebula, and the epochs are to look for variability in the nebula.
The star is a long-period variable which should close to peak brightness but this
prediction could be off. The star may be magnitudes fainter or brighter than appears
from the dss-2 finding chart.

Is this a Pre-imaging run ?
Pre-imaging Requirements
Source(s) of Pre-imaging
Pre-imaging sources not listed above
Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
