PHOTOMETRIC CCD OBSERVATIONS OF VARIABLE STARS
------------------------------------------------------
CENTER FOR BACKYARD ASTROPHYSICS (CBA) DENMARK
Observer : Lasse Teist Jensen
Address : Suhrs Alle 5, DK - 3520 Farum , Denmark
E-mail : ltj@tt.dk
Instruments: 0.25-m f/6.3 SCT , ST-6 SBIG CCD
Dear Colleagues,
Selected CCD results:
1137+72 DO DRA 2450374.4673 1996-10-17 0.9673 10.83
1137+72 DO DRA 2450376.4784 1996-10-19 0.9784 11.63
The first run (3 hours, 17-18 Oct) shows a smooth curve with a peak at the
end.
The second run (4 hours, 19-20 Oct) clearly shows a couple of humps. This is
a bit odd (as I remember it
the orbital period is about 4 hours). At both nights the runs were stopped
by thick haze.
Regards
Lasse Teist Jensen (JLT)
