Description:
Photometric and interferometric observations of the [OI] 630nm emission were made at a field station near Albany (42.68°N, 73.82°W), New York, and the thermospheric temperatures were derived from Doppler line profiles of this emission. The [OI] 630nm profiles observed around 0700 UT on July 5, 1978, which showed the most increased “apparent temperatures”, could not be interpreted in terms of a single Gaussian source profile. Instead, a combination of two Gaussian source profiles satisfactorily explained the observed results. This, together with unusually high intensity at the time of the observation, suggests that the [OI] 630nm emission consisted of two different components, each being originated from a different source. © 1986, Society of Geomagnetism and Earth, Planetary and Space Sciences.
