Planning, Executing, Wrapping up your run at CTIO

Before your run:

For YOUR Information:

For OUR Information:

  • Once you have arranged your trip, please let us know your Travel Plans.
  • Please tell us the instrument setup you need by filling in the visitor support questionaire.
  • Please consider giving a talk -- CTIO staff are always interested to hear what others are doing in the astronomical community.

During the run:

Our mountain observing support staff provides most of the support for observers on Cerro Tololo itself. For the V. M. Blanco 4-m Telescope, each instrument has a scientific staff contact for additional help. The smaller telescopes are operated by the SMARTS Consortium, and queries should be directed to SMARTS personnel.

At the end of every night at every telescope, a report form must be filled out. At all telescopes this is the responsibility of the observer. The observing assistant (Blanco, SOAR) will remind the observer to fill out the form as necessary. For the Blanco and SMARTS Telescopes the forms are here. At SOAR, the forms are available here. At SMARTS telescopes, please follow their protocol.
