Abstract
Temperatures of the equatorial thermosphere were obtained from the rocket released vapour clouds during (i) geomagnetically quiet and (ii) just after (<2 hrs) a sudden commencement. These measurements of thermospheric temperatures at different altitudes during sudden commencement are the first of their kind. The results reveal larger temperatures (>400 - 500° K) than that expected by the Jacchia 77 model during disturbed periods, while the quite day measurements agree well with the model predictions. The possible sources of energy that account for the excess temperatures are discussed in the context of the present measurements.
