\IBVSTrem{
The variability of GSC 01343-02414 was discovered during a CCD survey 
searching for new variable stars from Mollet Observatory from 22 November
2001 to 10 March 2002, and observed with the 0.6m Cassegrain telescope 
from Esteve Duran Observatory. This object is listed in the Guide Star 
Catalogue with a PAL-V1 photovisual magnitude of 12.61. Our observations 
show that GSC 01343-02414 is a new EB eclipsing binary system with a 
period of 0.57 days (Figure 1). The star fades 0.40 magnitudes at 
primary minimum and 0.19 at the secondary one. The following ephemeris
 was computed:
\[
\begin{array}{r@{}r@{}l}
{\rm HJD}_{\rm MinI} = 2452327\fday425 & {} + 0\fday56914 & {} \times E. \\
\pm0.005 & \pm0.00007 & \\
\end{array}
\]
