V2540 Oph (Nova Oph 2002) is a classical nova discovered by Katsumi Haseda and Yuji Nakamura on 2002 January 24. The light curve of this nova shows strong post-outburst oscillations as were observed in V1178 Sco and V4361 Sgr. Accurate astrometry of the nova yeilded an upper limit of 21 mag for the nova precursor. In combination with the observed decline rate, We propose that the nova should have either a short orbital period or a high inclination. We suggest that V2540 Oph may be analogous to V2214 Oph, a presumed magnetic nova inside the period gap.
