During the night of August 5/6, 1989 for the first time a noctilucent cloud (NLC) was detected and measured by a lidar instrument. The NLC developed at about 22:20 UT, reached its maximum backscatter cross-section at 23:05 UT and became unobservable at around 00:10 UT. During this period, the NLC exhibited the following properties: (1) its altitude ranged between 83.4 and 82.2 km; (2) its full width at half-maximum ranged between 1.4 and 0.3 km; (3) the ratio of measured backscatter intensity from the NLC to the calculated Rayleigh signal from 82.6 km reached 450; (4) its volume backscatter cross section maximized at 6.5 x 10 to the -9th/m/sr.
