Request for observations

I am trying to organise a short observing campaign on the 11th magnitude
eclipsing binary V1147 Cyg, which lies close to Chi Cygni. Recent CCD
observations show an eclipse of 0.7 mag, lasting about 5 hours. The star
is normally at V ~ 11.5. Several estimates of the period have been
published but they are all wrong. What we need are some visual
observers,
who can reach at least V = 12, and who might be interested in looking at
this star for perhaps a month or so. The observers need to be
distributed
around the globe to obtain maximum coverage. Observers on the Pacific
rim
and Hawaii would be particularly valuable. If any eclipsing binary
observers are interested you can find further details, finding charts
etc., on my web page
