All As pointed out by Patrick Schmeer, it appears that I may have been observing the minor planet 264 Libussa which was very close to the position of HV Vir at the time of my observations. I have made follow up observations over the last hour and have yet to detect any motion. However if the brightness of the minor planet is around 13.3, then this is the object that I have been observing. I must admit that I thought it slightly odd that the posiiton of the object was very slightly different from HV Vir's position as shown on the RASNZ VSS chart, but thought that the chart may have been slightly in error. I apologise for any inconvenience this may have caused and thank Patrick for pointing this out. These pesky asteroids!! Regards Andrew Pearce Western Australia
