The Beijing Astronomical Observatory (BAO) 0.6m telescope has been used for nearby supernova survey in more than 3000 fields,covering a total area of 235 deg^2,More than 260000 CCD images have been collected since April 1996,with 45 supernovae discovered,We searched for variables in about 90 000images taken during 1996-1998.For the fileds in which long period variables(LPVs) were discovered,we reduced further images taken from 1999 to 2000,for the period estimation.Among the 280000stars selected from the survey fileds,i.e., brighter than 18mag,we discovered seven new LPVs and reconfirmed three known LPVs.Additionally,we found 146 variable star candidates,and reconfirmed about 20 previously known or suspected objects.
