The PLANET collaboration updates this list daily (well, almost . . .)
during PLANET observing periods, using its on-going observations performed
at four
southern observatories . Where PLANET data is incomplete, supplemental
information from the
MACHO Alert Page is also used. This updated database is provided
as an aid to observers. Although every effort is made to maintain its
accuracy, PLANET cannot guarantee the validity of any of these
preliminary data.
