Request for Observing Time

In this page the astronomers will find electronic forms to ask for observing time at CASLEO. If you only want to visit our facilities, either during the day or the night, please do NOT use these forms. In that case, go to Outreach Activities.

Usually, proposals for observing time allocation for the February 1 - July 31 semester should be submitted until September 30 of the previous year, and for the August 1 - January 31 semester, proposals are received until March 31, but always ask about the correct dates because they could change.

Before submitting your request for observing time, please read carefully the section Norms and Regulations.

You will find here the on-line form to apply for observing time at the following telescopes: "Jorge Sahade" (JS), ASH, THG, and Solaris, for semester 2018A (Feb-Jul, 2018). For further instructions (Spanish only), please click here. The deadline to submit your proposal for semester 2018A has been moved to October 15th, 2017. Please, send any further questions to turnos(at)casleo.gov.ar

Service Observing

CASLEO offers observers the possibility to request service observing for the JS telescope. Please contact us at turnos(at)casleo.gov.ar for details.

Observing Run Report:

In order to provide a better service to the observers that visit CASLEO is important that they fill a report with their opinions regarding several points of interest for our technical staff. The report should be sent from your own e-mail address to turnos(at)casleo.gov.ar and it will be for Exclusive use of the Director.

Report models with updated questions can be found at this link for "Jorge Sahade" Telescope or at this link for "Helen Sawyer Hogg" telescope.

Remember that this report does not replace the information that is included in the telescope daily report and please do not use forms from previous semesters because it is possible that the questions asked be different.
