Mt. Saraswati, Hanle

Call for Proposals

The 2-m Himalayan Chandra TelescopeThe 2-m Himalayan Chandra Telescope (HCT) at the Indian Astronomical Observatory (IAO), Mt. Saraswati, Digpa-ratsa Ri, Hanle at an altitude of 4500 m (15000 ft) above msl is operated by the Indian Institute of Astrophysics (IIA), Bangalore. It is remotely operated using a dedicated satellite communication link from the Centre for Research & Education in Science & Technology (CREST), Indian Institute of Astrophysics, Hosakote, about 35 km northeast of Bangalore. The Himalayan Faint Object Spectrograph Camera (HFOSC) and the TIFR NIR Spectrometer and Image (TIRSPEC) are available for regular observations. The Telescope is available to the astronomical community. The Observatory accepts Target of Opportunity proposals, and Guest astronomers may need to accommodate such programmes in a part of their allotted time.

Some time is reserved for preventive maintenance of the telescope and instruments (scheduled around full moon), and for Observatory programmes.

The HCT Time Allocation Committee (HTAC) has been constituted by the Director, IIA, with D.K. Ojha (TIFR, Chair), M. Gopinath (ARIES), Shashikiran Ganesh (PRL), G. Pandey (IIA), A. Goswami (IIA) and D.K. Sahu (IIA) as members. HTAC invites observing proposals from astronomers.

Proposals are called for three times a year. The three cycle periods and their corresponding deadlines are given below.

Guest observers can operate the telescope and instrument from CREST using the satellite communication link. There could be occasional problems at night which can be attended by experts only during the following day.

Proposals and queries may be sent to htac@iiap.res.in.

HCT accepts proposals under "Director's Discretionary Time". Objects that fall within accepted proposals (regular, time critical and/or ToO) are not eligible to be considered under DDT. All DDT proposals when submitted to HTAC should contain “DDT proposal” in the subject.
