TV Col Outburst

    An outburst of TV Col was reported to us by M. Linnolt (V=12.2, 
7:50UT 9 Mar.).  We have started time-series optical and infrared 
observations with the KANATA 1.5m telescope, and confimred the outbutst.

    TV Col is an intermediate polar (IP) showing dwarf nova-type outbursts.  
Its outbursts have very short durations compared with ordinary 
dwarf novae.  Some other IPs, for example, HT Cam and DO Dra, also 
exhibit such short outbursts.  So, those short outbursts may be 
related to their IP nature.  

Follow-up observations are urged.
