  • The period of low solar activity between solar cycle 23 and 24 last a long time, having low F10.7 and long-term sunspot number record. So it is the time to study the change of upper atmospheric density in this quiet solar and geomagnetic activity conditions, especially for study of the response of upper atmosphere to variations in small geomagnetic disturbance and low solar activity. Atmospheric density detector mounted on the satellite near 650km aims at getting measurement data with the change of geomagnetic and solar flux variability, whose data are available ranging from 2007 to 2009, the results are concluded as follows. Upper atmospheric density obviously responses to the F10.7 variation in condition of low solar activity. When F10.7 decreases from 70 to 65, daily atmospheric density decreases obviously for 4~5 times, which is much larger than the decrease in the model. Upper atmospheric density also obviously responses to the small geomagnetic disturbance. Atmospheric density is increased strongly by 80%~160% when the sum of Kp increases from 23 to 30.
