  Title: MULTIBAND OBSERVATION OF BRIGHT BL LAC OBJECT MKN501                            


Abstract:
 We propose to observe the BL Lac object Mkn501. This object is the second TeV gamma
 ray emitter recently detected by Whipple Telescope after Mkn421. Our multiband
 observations of Mkn421 in AO2 and AO4 have shown the simultaneous xray and TeV
 flare. It is hard to explain both X and GeV/TeV emission by the standard model(SSC).
 In order to understand the emission from ``TeV'' blazar, xray observation is
 crucial. Because of the high time variability, we propose to coordinated multiband
 observation from radio to EGRET(GeV) and Whipple telescope(TeV).
