[39.03] Nightside Venus Atmospheric Circulation from Nordic Optical Telescope Observations

J. Warell (Upsala University, Uppsala, Sweden), S. S. Limaye (University of Wisconsin-Madison, Madison, Wisconsin, USA), E. F. Young (Southwest Research Inc., Boulder, Colorado, USA)

Near infrared observations of Venus' nightside hemisphere were acquired from the 2.6-m Nordic Optical Telescope at the Roque de Los Muchachos Observatory located on La Palma, Canary Islands, Spain during May ( 117 - 126 degrees phase angle) and August 2004 (86 - 80 degrees phase angle). The May (3-10) run was coordinated with other globally distributed observatories, enabling tracking of cloud features over a longer temporal baseline (see Young et al. abstract, this conference)than possible from a single site. The observations, mainly in the 2.1 micron K-band, were aquired to allow a study of the atmospheric circulation pattern and and cloud evolution, partly to support the European Space Agency's Venus Express mission.

Other participating observatories include, the 2-m Himalayan Chandra Telescope at Mt. Saraswati, Hanle, Indian Astronomical Observatory, the 1.2-m Mt Abu Telescope of the Physical Research Observatory, the Sacramento Peak Observatory, National Solar Observatory, New Mexico, USA, and the 3.6-m NASA Infrared Telescope Facility, Mauna Kea, Hawaii, USA. We gratefully acknowledge the staff at NOT and the Wenner-Gren Foundations and the Swedish Research Council for making these observations possible.
