[vsnet-alert 615] EG Cancri's latest deeds

[jop@astro.columbia.edu (Joe Patterson)]

THEY have arrived.

The photometric waves in EG Cancri that Taichi Kato sensed as they were
passing Pluto (how does he get his information?).

During a CBA-Maryland run of six hours centered on December 5.35 UT,
the waves were at 0.027 mag and slightly growing.  A Cerro Tololo
observation on December 6.3 showed that the amplitude had grown to
0.13 mag (at V=13.0), and on December 7.3 it had grown further to 0.18
mag while the star had brightened to V=12.5.  The period was probably
0.0606+-0.0002 d, with a chance of really being 0.0645 d, the one-day
alias.  In either case, quite a bit longer than the period(s) reported
a few days earlier.

Won't you join us in watching this fascinating little star which is
likely to teach us a lot during its four weeks of fame...
