Estimated Total Execution Time (hours, including overheads)
General Description
For this observing run we need to obtain visible spectra for 9 asteroids
by means of VLT (FORS2) for a total of 10 hours. We need to use the filter GG435.
********Calibration********
For every asteroid observations we need to acquire spectra (i.e. calibration) for
1 standard star. It is ABSOLUTELY NECESSARY that the calibration star is observed
during the same night as the asteroid and just after the object with similar atmospheric
conditions and similar airmass. Indeed, each of our OBs includes: ASTEROID + Calibration
Star. Our waiver request has been accepted which will allow us to have our asteroids
and stars observed consecutively.
*******Targets*************
The asteroids are: 1270, 60151, 89309, 2003 SQ168, 14627, 1992 YC2, 21509, 2003
VM9, 2004 XL40.
1) All the targets and calibration stars should be observed with an airmass under
1.7
The only exception is for the asteroid 14627 which can not be observed at optimal
airmass. Anyway, we ask that the asteroid is observed with an airmass under 1.9
2) The targets should be observed close to opposition which will minimize the exposure
time for each target.
We do not add finding charts since for these Moving Targets we would have to produce
a very high number of charts.
The support astronomer can either use DSS or the following website in order to find
the asteroid:

Dear PI,
I wish to inform you that your WAIVER request for observing programme
380.C-0241 has been granted with the usual restriction that if the conditions
degrade in violation of the constraints after the first hour, the OB
will not be repeated.
Best Regards
Dr Magda Arnaboldi

Dear Eso staff,
We ask that our OBs (true for 4 targets among 10) exceed 1h05
in order to reach the required S/N.

Critical Observing Condition Constraints
All the targets and calibration stars should be observed with an airmass
under 1.7
The only exception is for the asteroid 14627 which can not be observed at optimal
airmass. Anyway, we ask that the asteroid is observed with an airmass under 1.9
Moreover:
After each asteroid observation, a standard star (calibration) should be observed
! This immediately after the asteroid, in order to ave similar atmospheric conditions.
This is essential and greatly affects the outcome.
Time-Critical Aspects
Our objects need to be observed close to oppostion because they are brighter
there and with an airmass under 1.7. The only exception is for the asteroid 14627
which can not be observed at optimal airmass. Anyway, we ask that the asteroid is
observed with an airmass under 1.9.
For each object, we list the OB name, the starting date and ending date (i.e. time
intervals).

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 ?

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 ?
