General Description
This observing program is a direct continuation of earlier semesters
programs 70.D-0607(A), 071.D-168(A),072.D-0524(A),74.D-0141(A). We monitor the
recovery of so called spectroscopic event of Eta Carinae over the time from
April to October 2006.
Eta Carinae will in this phase continously change its spectrum (and
brightness).
During the earlier observations Eta Carinae has been continously monitored
during the event (the minimum, as lines dissapear; June/July 2003)
and now the spectrum should recover.
We are observing 2 different position (called FOS4 (3 times) and STAR (2times))
with both dic1 and dic2 and short and long exposures.
OBs are named as follow ETA CAR FOS4 no1 dic1
to identify this is observing eta car on position FOS4, it is the first
(of 3) observations in the dichroic 1. All other names are analog.
We need not to have exact observing dates but observations
should be made in a roughly two-month separation, in
resonable long time intervals (e.g. NOT one spectrum an 30.April
the next on 1.May...)
We observe a special region (FOS4) within the nebula around Eta Car
which shows the reflected stellar spectrum.
To peak up to the FOS4 position we are using an
offset star north-east of this position.
A guide star and a finder chart for the guide star is given.
The guide star's designation is U0300_10504917
the position 10:45:12.898 -59:44:19.32 V about 12.1.
It would be VERY good (but is not stricktly necessary) if the observation of FOS4
could follow the observation on the STAR after about 2 weeks, as this is
the light travel time from STAR to FOS4. Such a timing of the observations would
help
the analysis tremendously.
Waiver Requests
Critical Observing Condition Constraints
Time-Critical Aspects
Time constraints have NOT been included in the OBs in
p2pp. This was done because the observations are not critical to a
certain DATE but more to a special TIME INTERVAL (see also general desciption)
The spacing between each observing block does not have to be
absolutely the same each time, but we would like to have a time
coverage as good as possible, so spacing the observations equally
within the 6 month (about every 2 month one taken).
If possible FOS4 observations should follow STAR observations after about 2 weeks.

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 need secondary guiding, are there suitable objects within 30 arcsec
from your target ?
