DAMP04

Hello everyone,

We've completed the first stage of Damp04.  Things are fairly quiet
right now, with only two sites observing.  Things will start to pick
up again in a few days as more telescopes come on line in the middle
of May.

We have a very nice light curve of GD358, along with some preliminary
data on WDJ1524, EC14012, and the KIC10139564.  Take a look at the
website (https://ms10.nss.udel.edu/wm/mail/fetch.html?urlid=0523e2a48046fdfab00361f80566c426b&url=http%3A%2F%2Fdarc.physics.udel.edu%2Fwet%2Fdamp04%2Fphptools%2Findex.php)
under "Interesting Plots" to see the current light curve, FT, and a
few other interesting plots.  We have filled nearly every gap at a
least once, especially at the beginning of the run, so the spectral
window is decent, although the one day aliases have been growing back
in.

One of our goals with GD358 is to resolve the k=8 and 9 multiplets,
the only two of GD358's modes that are always triplets. We have
achieved this goal, and the resulting figure is given on the website.
This figure monitors the width of the k=8 triplet, and the m=(0,1) and
m=(0,-1) splittings since 1990.  The asymmetric splitting can change,
as it did during the 1996 "event" known as the whoopsie.  This year,
both splittings are nearly symmetric.  The physical reasons are
unclear, but the k=9 and 8 modes do seem to be behaving in interesting
ways, as shown in the travelling FT figures also on the website.

We will continue monitoring GD358 as the run continues, as well as
obtaining more observations of EC14012 and WDJ1524.

Cheers,
Judi
