Dear Colleagues,
Selected CCD results:
2137+48 V1251 CYG 2450709.4416 1997-09-17 0.9416 16.4
2158+41 BL LAC 2450709.4472 1997-09-17 0.9472 14.3
0104+27 VAR PSC 2450709.4534 1997-09-17 0.9534 15.2
0211+40 KV AND 2450709.4569 1997-09-17 0.9569 14.7,
outburst
0036+26 LL AND 2450709.4604 1997-09-17 0.9604 <16.0
0457+26 HW TAU 2450709.4777 1997-09-17 0.9777 <16.5,
Downes, Shara and Webbink position.
I remember Taichi Kato asking a while ago whether this position is
correct. Any conclusions ?
1925+54 USNO 1425 2450709.2826 1997-09-17 0.7826 14.9, a
3.5 hour time series didn't reveal superhumps.
So if the superhumps still persist then the amplitude is probably less
than 0.1 mag.
I did another time series last night. Not reduced yet, but the mag is
still around 14.9.
Regards
