Abstract

Time series for this cataclysmic star are presented during its 2006 (super)outburst.

Introduction

EG Aqr is a cataclysmic viariable, that is a binary with an accreting white dwarf star. It was observed as being in (super)outburst on Nov 8, 2006; this is the 3rd known (super)outburst for this system (previous ones in 1958 and 1959) (IAU Circulars CBET734 and CBET736).

This is a CBA target during the 2006 outburst.

Observations

The observations were carried out with a 203mm SC telescope, a Clear filter and a SBIG ST7E camera (KAF401E CCD). Each exposure has a duration of 60s. 285 images were obtained.

The comparison star is GSC 5822-00406 with an assumed unfiltered magnitude of 12.000 and the check star is GSC 5833-01012 with a standard deviation of 0.027 mag.

Red: EG Aqr, Blue: the check star shifted by -0.3 mag. The error bars are +/- the 1 sigma statistical uncertainties.

The outburst is over. The check star is shifted by +3.0 mag.
