- XCOV 25 , held in May 2006, was the first WET run sponsored by the Delaware Asteroseismic Research Center and Mt.Cuba Observatory. To view the results of this run, go to XCOV 25 Website. The results are now
published. Check out our publications list below.
- The results from the 2008 campaign on G29-38 are now published. Gemini obtained time-resolved spectroscopy, and ground based telescopes obtained extensive optical observations. The data show some interesting results concerning the distribution of calcium on the surface of G29-38. Check out the publication listed below.
- XCOV27 is now under analysis. Information on the data set, including light curves and
FTs, is given at XCOV27. Check out the XCOV27 Google Group for pictures from participating observatories.
- XCOV28 is now under analysis. Information on the data set, including light curves and
FTs, is given at XCOV28.
- XCOV29 is coming up in April and May 2013. Information on the run, including telescopes and targets,
can be found at XCOV29.
- DARC Home Page is at DARC.
- We are always looking for interesting targets. There is no formal application
process. If you have an interesting target that you think needs WET, please
send the info (the target name and a couple of paragraphs concerning the
scientific goals) to Dr.Judi Provencal or
anyone on the advisory board, or go to Target Proposal.

The Whole Earth
Telescope (WET) is a collaborative effort between astronomers
all over the world who are interested in studying the variability of
astronomical objects. Objects that vary continuously require constant
monitoring in order to unambiguously measure the intrinsic variations,
which is impossible from a single site on Earth. The WET was one of the
first worldwide collaborations of this type, and continues as an
example of international cooperation in astronomy. This website
contains information about the history, activities and publications of
the WET collaboration.
