Sondrestrom Lidar Operation Log

Operator(s) : E.Gudmundsson, K.Richmond, T.Jorgensen
Purpose : Sodium data collection in conjunction with the IS Radar
Date(s) : 000221 - 000222
File(s) : L2210 - L2221
Comments : First run after the intallation of the 4x beam expander

Note. The telescope iris is at minimum apperture and we are getting very nice
sodium counts!
