The Whole Earth Telescope (WET) is a collaboration of astronomers who observe variable stars (white dwarfs and Delta Scuti stars) and cataclysmic variables Typically twice a year, we coordinate a global time-series photometry campaign at ~10 observatories worldwide such that our target objects are visible from the night side of the planet 24 hours a day - Categories: telescope survey

Wide Field CAMera for UKIRT (WFCAM)
WFCAM is an IR wide field camera for the UK Infrared Telescope on Mauna Kea. WFCAM will be operational as an IR imaging survey instrument in late 2002. The camera has been designed to maximize survey speed at J, H and K while retaining excellent image quality. - Categories: survey infrared telescope

Wisconsin H-Alpha Mapper (WHAM)
The Wisconsin H-Alpha Mapper will produce a survey of H-Alpha emission from the interstellar medium (ISM) over the entire northern sky. The instrument combines a 24-inch telescope and a high-resolution, 6-inch Fabry-Perot spectrometer to achieve 8-12 km/s velocity resolution in one-degree beams on the sky. By utilizing CCD technology, we hope to attain a sensitivity level of 0.01 Rayleighs. This survey, the first of ionized hydrogen in our galaxy, will be used to explore the spatial and kinematic structure of the warm ionized component of the ISM. WHAM is currently at Pine Bluff Observatory but will move to Kitt Peak, Arizona in the Fall of 1996 for the survey, which should take about 2 years. - Categories: survey optical
