Optical photometry and UV spectroscopy of the flare star GL 735 (= V1285 Aql)
Optical photometry is presented for flares and possible spot variationson the star Gl 735. Consideration of the energetics of the opticalflares suggests that the star may be underactive when compared to otherflare stars of the same spectral type. This conclusion is not supportedhowever by an estimate of the radiative loss rate from the lowerchromosphere due to Mg II h and k. Radiative losses from the upperchromosphere, transition zone and corona are also normal for a flarestar of its spectral type.
