Damp04 Update

  Hello everyone,

Damp04 is moving right along!  We have been dealing with clouds, fog,
thunderstorms, telescope issues, ccd problems, and even some injuries!
But the data are still coming, and our targets are looking very
interesting.

We are now getting ready to enter the second busy part of Damp04.  We
have some very interesting data so far.  GD358 continues to be very
challenging.  If you go to the website and click on "Interesting
Plots" you will see our most recent GD358 light curves and FTs.  There
is a plot that compares the GD358 FT for the first part of the run
(until ~May 12) to the newer data (May 16-19).  We had two days with
clouds and no new GD358 data.  The peak at 1735.7 microhz is mostly
unchanged (1735.783 on May 12 vs 1735.987 on May 21) but we can see
several differences.  The 954 microHz peak has increased from 2 mma to
15 mma.  The 1247 microhz peak has behaved similarly (2mm on May 12 to
15 on May 21).

EC14012-1446 is also very interesting.  This star was a 2008 XCOV27
target.  The main frequency is 1633 microhz, one of the two largest
frequencies observed in 2008.  However, its amplitude is now a
whooping 54 mma, over twice as large as observed in 2008.

Aleksandr has sent some wonderful pictures from Terskol, which I've
attached. Peak Terskol is a very beautiful place.  We also have a
story from Willie Strickland at PJMO in Texas.  I don't if everyone
remembers, but last year Willie had some surprise visitors to PJMO
(see Unwanted Guests).  The guests were fortunately more interested in
the baby birds.  This year Willie removed that tempation by placing a
styrofoam cup to keep the birds away:)

We have started a blog for this run.  If you go to the run page and
click on "WET BLOG"  it will take you there.  It is still under
construction, but please check it out:)

Cheers,
Judi
