It is very important to locate correct observation site before installing sprite-watch system. For observing sprites a clear view above thunderstorm systems is required. This generally means the thunderstorm activity must be on the horizon. Additionally, there must be very little intervening cloud cover. Best viewing distance from storm is 100-200 miles (200-300 km). At these distances sprites will subtend a vertical angular distance of 10-20 degrees. It must be dark.

Campaign B
The remote observations were done using the system set up at two different locations by Danish Space Research Center. Operators themselves were in Leicester during their observation periods.
