Estimated Total Execution Time (hours, including overheads)
General Description
The aim of this program is to obtain optical spectra
of the T Tauri star V1647 Ori,
as close as possible in time with CRIRES NIR spectra (run A).
Our goal is to study the behavior of the
Halpha, Fe II and Ca II lines,
simultaneously with the NIR emission features of H2 and CO.
OB's for three epochs are included because CRIRES data
will be taken in three epochs.
The observations are standard FORS2 long-slit observations.
We employ the grism 1200R and 1028z with a 1" slit.
The object is V1647 Ori, a young variable star that suffered an outburst in august,
it expected to be its brightening phase.
Last reported R band mag was 17.8.
Exposure times are computed for obtainnig at least a S/N 20 for
a R=18 star.
We note, that north of the target a bright nebula is present (see attached figure)
The slit is oriented north-south.
Waiver Requests
Critical Observing Condition Constraints
Time-Critical Aspects
Monitoring observations to be executed coordinated with CRIRES observations
(run A).
FORS2 observations should be executed simultaneously,
prefentially between a few days of the CRIRES observations.
The program is a monitoring program.
We requested data in three epochs spaced 1.5+-0.5 months:
The first epoch to be executed as soon as possible (October, OB V1647_Ori_FORS2_epoch1)
The second epoch to be executed in November-December (OB V1647_Ori_FORS2_epoch2)
The third epoch to be executed in January-February (OB V1647_Ori_FORS2_epoch3)

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 ?
If you have prepared your finding charts with tools other than FIMS,
do they comply with the specifications on the FORS1 Phase 2 web page ?
