Hey, all. The baseline data is starting to come better. Thanks to
Charles Knapp, Gary Walker, Mike Koppelman, and Robert James. We're
heading in the direction of writing two papers on this campaign. Greg
Laughlin will use the results in his exoplanet work and the AAVSO will
publish on the variability of IL Aqr (using archival observations and
current baseline data). So even though this campaign means alot of
work, it's worth quite a bit to the community! Please observe it once
a night in BVRI (or as many filters as you have) and perform a time
series run every few nights.
Quick note, Arne has posted in his .dat file a new location for IL Aqr:
22:53:17.03 -14:15:52.5 (2000)
There is only one week to go! The upcoming weekend is an optimal
time to practice and get some time series observations in. Work on
your precision and try to get a good 4 hour observing window in.
== Please Report Airmass ==
The redness of this star will be a problem, especially as it
relates to trends caused by airmass. Please observe in V! Also, for
those of you who know how to calculate your airmass, please report it
with your observations. Put AIRMASS= X in the "Comments" field of your
report (or the WebObs CCD Batch Upload form)
I will post a tutorial on how to determine your airmass in the
next few days.
== Need More Observers ==
We currently have 21 people from 7 countries signed up for the
campaign. We need more!
This is a 3 evening campaign for most so we need redundant coverage in
case of poor weather, equipment, fatigue or life events prevent
someone from observing one night. Ideally we'd like to have 3 people
able to observe at any given time.
Desperately need observers:
05:00 - 09:00 UT (central pacific)
15:00 - 19:00 UT (west asia/east europe)
Have sparce coverage, need much more:
15:00 - 23:00 UT (asia and europe)
Need more observers to provide extra redundancy:
Entire campaign!
All times are for the entire campaign, October 20 11:22 UT - October
23 15:27 UT.
As always, light curves and more info updated many times a day here:

Please spread the word of this campaign through your local clubs,
observatories and organizations. The more, the merrier...
