From Science Daily:

ScienceDaily (May 20, 2009) — The Whole Earth Telescope (WET), a worldwide network of observatories coordinated by the University of Delaware, is synchronizing its lenses to provide round-the-clock coverage of a cooling star. As the star dims in the twilight of its life, scientists hope it will shed light on the workings of our own planet and other mysteries of the galaxy.

The dying star, a white dwarf identified as WDJ1524-0030, located in the constellation Ophiuchus in the southern sky, is losing its brightness as it cools, its nuclear fuel spent. It will be monitored continuously from May 15 to June 11 by WET, a global partnership of telescopes which was formed in 1986.
