General Information
La Silla Science Operations Department (LSO) is part of the La Silla Paranal Observatory
and is in charge of the operations of the telescopes on La Silla. These telescopes are:
the 3.5-m New Technology Telescope (NTT), 3.6-m Telescope, 2.2-m ESO/MPI Telescope.
Always carry your torch with you and flash it while walking during the night on La Silla. Be cautious, because cars are driven with very low illumination. If you did not find a torch in your room, please request one immediately at the Reception (phone 4192).

Information for Observers
In the La Silla Science Operation pages, you should find all the information you need
for your observations from the time you have an idea of observations until when you finish
processing your data. The menu on the left contains the list of the LSO pages for the astronomers,
which are described in more details hereafter. Also, some useful ESO pages (not belonging to LSO)
can be accessible from the left sub-menus and are explained in this page.
Preparing your proposals for observing time and your observations
Visiting astronomer coming to La Silla
- The presence of the Visiting Astronomer at LA SILLA before
the start of the observations depends on the transportation schedule.
As of Period 84 (October 01, 2009) ground transportation between
the observatory and the airport in La Serena and vice versa will be available
on Mondays, Wednesdays and Fridays only. In general, the Visiting Astronomer
will arrive 1 to 2 days before the start of observations,
and may leave the site up to 1 to 2 days after the observations.
- Before your observation run: you should familiarise yourself with the technical documentation
(see below), and with P2PP. This Visitor Information page
contains the info you will need. From that page, you will also find informations on the
Data Reduction Facilities and e-mail at your disposal.
Remember to prepare
- a backup program in case of poor seeing, thin clouds or strong winds (usually
implying targets with Dec <-25 deg),
- the list of additional objects you want to observe in addition to your approved targets
and to request their approval well
in advance using this procedure
NEW - Jul.2007 - requests have to be sent using
the webform included in the updated procedure
|
- Arriving on La Silla, you should also check out the practical information you should find in
your room (or here as a PDF file)
