| Zusammenfassung |
| Measurements of the hydroxyl rotational temperature for the (8,3) Meinel
band have been reported from the observations of the ratio of the relative
intensities of P1(2) and P1(4) lines of the OH(8,3) band at
Kolhapur (16.8° N, 74.2° E, dip lat. 10.6° N) in India during the
period 1 November 2002-29 April 2003 using tilting-filter photometers. Mean
values of rotational temperature have been computed for 60 nights. The
monthly mean value of temperature lies in the range 194(±11)-208(±18)K.
The mean rotational temperature obtained from all the measurements
was found to be 202±15K. The results agree with other low-latitude
measurements of rotational temperature using photometric airglow techniques.
Quasi-periodic fluctuations with a period of about one to two hours have
been prominent on many nights. Furthermore, the results show the general
agreement between observations and model (MSIS-86) predictions. |
