Abstract:
    We present charge-coupled device (CCD) photometry for the short-period
    K-type binary EI CVn, observed on 2009 February 28 at the Xinglong
    Station of National Astronomical Observatories, Chinese Academy of
    Sciences. By using the Wilson-Devinney program, the photometric
    solution was first deduced from our VR observations.

Description:
    New Photometry of EI CVn was carried out on 2009 February 28 using the
    60-cm telescope at the Xinglong Station of the National Astronomical
    Observatories, Chinese Academy of Sciences (NAOC). The photometer was
    equipped with a 1024x1024 pixel CCD camera. Each pixel subtends a
    projected angle on the sky of 0.996", which results in a field of view
    of 17'x17'.
