Subject: BL Lacertae campaign

Dear WEBT (and other) observers,

we are organizing an optical campaign on BL Lacertae contemporaneous
with the high-energy campaign involving X-ray and TeV observatories such
as BeppoSAX, RXTE, STACEE, CAT, HEGRA.
Our purpose is to monitor BL Lac in the optical bands from one week
before to one week after the high-energy campaign, that is from July 17
to August 11, with particularly dense coverage in the central period. We
hope to get collaboration from observatories located at different
longitudes, in order to obtain as continuos as possible light curves
during all 24 hours of each day. In particular, our goal is high-density
and high-precision coverage, possibly in two optical bands (B and R).
Observers interested in participating to this optical campaign are
invited to contact us replying to this message, and providing a few
information on their instrumentation (telescope, detector, filters) and
possible observing period.
More detailed observing strategies will be discussed with the interested
people.

Thank you for your attention,

Massimo Villata, Gino Tosti, Enrico Massaro
