Observations of Venus in Near
Infrared, 3-9 May 2004
Coordinated
observations of Venus at 1.73 and 2.29 microns are planned from IRTF
(Young and Bullock), Nordic
Optical Telescope (Warell, Limaye and Fry), Himalayan Chandra
Telescope (Limaye, Prabhu, Fry, Young and Emerson) and
Mt. Abu
(Limaye, Fry, Warell and Young).
The Observations from the 2-m Himalayan Chandra Telescope at Mt. Saraswati, Hanle, Indian Astronomical Observatory, the high altitude station of the Indian Institute of Astrophysics, Bangalore are made possible through the kindness of the Indian Astronomical Observatory. We thank the staff at IAO and at the remote control station at CREST, Hosakote for assistance during the observations.
The
observations from the 1.2m Mt Abu Telescope operated by are made
possible through the support of the staff and scientists of Physical
Research Laboratory, which operates the telescope. We are thankful to
them for their support.

Bangalore, India operates the Indian
Astronomical Observatory. One of the telescopes at this
observatory is the 2m Chandra
Optical-Infared Telescope located in Hanle Valley in Ladakh. The
telescope is operated remotely from the Centre for Research and

The
Mount Abu Infrared Telescope is the first major facility
in India specifically designed for ground based infrared
observations of celestial objects. The telescope is located near the
hill resort Mount Abu in the
state of Rajasthan in western
India. The observatory is at an altitude of 1680
metres adjacent to Gurushikhar - the highest peak in the whole
of central India.
