The coronal electron temperature was determined for the first time from the shape of weak depressions at 3900A and 4300Aai in the continuous coronal spectra.It was found that the coronal streamer has overall temperatures of about 1.5–1.7 MK, while the coronal hole has evidently lower temperature of 0.9–1.1 MK.No significant height variation of the temperature was found in the streamer, while the coronal hole shows evidence of increasing temperature with height. An acceleration of the expanding motion between 1.1 R ⊙ and 2.0 R ⊙ by ∼ 80 km s−1 was found in the streamer.
