This consists of combined local E and F region measurements. The Local 10 Position experiment will be run at night. This will include measurements taken in 10 directions to allow estimation of spatial gradients. A single fixed position to the north provides high time resolution. This may be replaced by a short azimuth scan as conditions warrant.
Geomagnetic activity is required.
The times and experimental modes to be run, as described in this letter, are all subject to change. This operations letter is sent monthly by e-mail to a limited distribution list. Created September 30, 1999.
