CI Aql report from Kral

Dear Colleagues,

   We have received four very(!) extensive (to circulate ...) sets of
time-series from Mr. Kral to the CI Aql VSNET campaign.  Thanks a lot!

(Comment from Kral)

I send You another results of CCD photometry of CI Aql, which was done 
at the Ostrava Observatory (http://ostrava.astronomy.cz).

The attached data files contain results of observation from each night. 
All this was performed using CCD SBIG ST-7 on a photo-lens (D=3D55 mm, 
f=3D600 mm) through a red filter of RGB (transmission characteristic can 
be found at http://vsnet.sbig.com/sbwhtmls/Oldfilterchart.htm)

The observation "ci2.dat" was provided by my colleague Tomas Havlik, the 
rest of the observations are mine.

The comparison stars were used the same in every cases (see the attached 
image). The comparisons are also the same as in the first dataset that I 
sent You before some time.

The variable seems to show no variability during these runs, except the 
"ci4.dat", where it seem to fade slowly. But this trend can be 
artificial - the weather at that night was not the best and also the 
comparisons show some little variability in that dataset.

We cannot make longer runs, because there in Czech Republic the star 
rises late at night and not very high above the horizon. However, I hope 
our data will help You in the research of that star.

Regards,
Lukas Kral
