Light curve for ST LMi

V2301 Oph has the weakest magnetic field White Dwarf yet detected in an AM Her system, so much so that it was originally thought to be an Intermediate Polar (see V2301 Ophiuchi: An X-ray-bright eclipsing AM Herculis Object. Cameron & Inamura, AJ 515: 404-413, 1999).  It's P_orb is 0.078450d (113.0m) and is an eclipsing system.  V2301 Oph is monitored as part of the BAA Long Term Polar Monitoring Programme.
