We present measurements of electron temperature and bulk flow speed low in the solar corona derived from white-light spectra obtained during the total solar eclipse of 2001 June 21. Observations were obtained at two locations in the solar corona, one within a helmet streamer at the east limb and the second in a streamer cluster in the southwest. Both points were at an altitude of about 1.1 Rsolar from the solar center. The east limb and southwest locations yielded electron temperatures of 0.96+/-0.05 and 1.2+/-0.2 MK and bulk flow speeds of 72.0+281.0-72.0 and 257.0+443.0-257.0 km s-1, respectively. These measurements are unique in that they simultaneously provide both the electron temperature and its bulk flow speed; few previous measurements of electron parameters in the corona are available. The results presented here demonstrate the potential for this technique: if the instrument were used with a coronagraph, it would provide routine synoptic maps of electron temperature and bulk flow speed.
