Forms for observing time applications at OSN can be written in spanish or english using different type of formats: pdf, doc or latex.
Applications must be submitted using the following application form.
Those observers who need to perform observations of unpredictable events (targets of opportunity, ToO) using the T150 and T90 telescopes, have to submit a application for observing time each semester. As all the proposals, they will be discussed by the Time Allocation Committee (TAC) of the OSN. Once the proposal is accepted, the PI will receive a list of rules that must be followed.
The PI of the accepted proposal should contact OSN staff (operadores-osn [at] iaa.es), sending the instructions of the ToO with the details of observation. The observations will be attempted whenever possible.
If there are several accepted projects and in case more than one ToO occurs in the same night, the OSN staff will decide how the triggers of the targets will be carried out in order to optimize the observing time.
When possible, a compensation of the observing time lost for the current program will be attempted. As an exception, if there is a critical program, i.e., in which the observation must be carried out in a specific night and hour, the trigger will NOT be performed.
OSN provides three observing modes:
The three modes can be requested in both the T150 and T90 telescopes. Observations in service mode will have higher priority at the T150 telescope than at T90, therefore, service observations in the T90 telescope are not guaranteed.
Important: Fraction of nights may be requested in observing proposals and may be shared with other programs when the same instrument and filters are used. Filters of both CCD cameras are not allowed to be changed during the night.
Observing log in doc format.
The use of OSN observations in any kind of publications must be acknowledged with the inclusion of the following text: "Based on observations collected at the Observatorio de Sierra Nevada, operated by the Instituto de Astrofísica de Andalucía (IAA-CSIC)".
Failure to do so may result in penalties being applied by the TAC for future proposal submission from the same PI/Co-I(s).
