Van Cauteren, de Borrekenslaan 54, 2630 Aartselaar, BELGIUM Internet: pvancaut@innet.be TEL. 32-3-8774098 =================================================================== V1113 Cyg [UGSU, 14p - <17p] ============================ Gary Poyner, Birmingham, UK reports an outburst detection of this little studied cataclysmic variable. Confirmative observations would be appreciated. 1995 04 19.028 UT, 13.7 (G. Poyner, 0.40-m refl., comp.star 13.6 Kato); 13.7 During the September 1994 outburst of V1113 Cyg, Taichi Kato (Ouda Station, Kyoto University, Japan) made V-band CCD photometry observations, that clearly revealed the presence of superhumps in the lightcurve. The super- humps had an amplitude of 0.23 mag (V) and a period a bit shorter than 2 hours [CVC 15]. Apart from this professional observation, we could trace no further information on V1113 Cyg. V1113 Cyg was last seen in outburst on January 31, 1995 by L. Szentasko, Hungary (unconfirmed observation), at mag 14.0 [CVC 27]. AL Com [UGWZ, 12.8v - 22v] ========================== Further to the photometric summary published in CVC 34, the table below lists additional outburst observations of AL Com. We express our sincere thanks to the many amateur and professional astronomers, who reacted on CVC 33 & 34, by submitting supplementary material on this UGWZ-type dwarf nova. ----------------------------------------------------------------------- DATE (UT) MAGN MS SEQ OBSERVER REMARKS SOURCE ------------------------------------------------------------------------ 1995 04 01.807 [15.3 mv * Yamada, M. 35-cm SCT priv(TAK) 1995 04 05.062 [13.9 mv BS * Jensen, L. 33-cm refl. priv(LTJ) 1995 04 06.677 12.0 mv * Yamada, M. 35-cm SCT priv(TAK) 1995 04 07.545 12.2 mv * Narumi, A. 15-cm refl. priv(TAK) 1995 04 07.549 12.4 mv * Yamada, M. 35-cm SCT priv(TAK) 1995 04 07.565 12.0 mv * Hiraga, M. priv(TAK) 1995 04 07.931 12.6 mv BS * Jensen, L. 33-cm refl. priv(LTJ) 1995 04 08.901 12.7 mv BS * Schmeer, P. 20-cm SCT priv(SCH) 1995 04 08.953 12.7 mv BS * Jensen, L. 25-cm refl. priv(LTJ) 1995 04 09.001 12.7 mv BS * Schmeer, P. 20-cm SCT priv(SCH) 1995 04 09.589 13.0V CV BS * Kato, T. 60-cm refl+CCD VSNET 1995 04 09.924 12.9 mv BS * Jensen, L. 25-cm refl. priv(LTJ) 1995 04 10.627 13.0V CV BS * Kato, T. 60-cm refl+CCD VSNET 1995 04 10.615 13.1 mv BS * Makiguchi, N. 25-cm refl. priv(TAK) 1995 04 11.913 13.2 mv BS * Jensen, L. 25-cm refl. priv(LTJ) 1995 04 12.635 13.3V CV BS * Kato, T. 60-cm refl+CCD VSNET 1995 04 12.917 13.2 mv BS * Schmeer, P. 20-cm SCT priv(SCH) 1995 04 13.510 13.5: mv * Yamada, M. 16-cm refl.? priv(TAK) 1995 04 13.465 13.4V CV BS * Kato, T. 60-cm refl+CCD VSNET 1995 04 13.86 13.8 mv * Kinnunen, T.
