SuperDARN Northern Hemisphere Orange and red-shaded radar fields are operational. Mustard and pink radar fields are under develop- ment or planned. Rankin Inlet will be operational by Spring Finland East and Hokkaido may be operational by Fall There may be 11 auroral zone and polar cap radars operational by Fall 2006 as well as 2 sub-auroral radars. Similar, but less extensive network in S. H.

SuperDARN Data Products Data products include: Vector electric fields Vector plasma drifts Global convection maps Measurements cover: Auroral zone Polar cap Subauroral regions. Complementary to: Satellite measurements Ground magnetic observations Ground optical measurements Data from Wallops Radar and TIMED/GUVI

Cluster/SuperDARN Coordination Hours of “Cluster mode”

Scheduling Approach Orbit/footprint plots originally intended for SuperDARN scheduling (Jim Wild, Leic. & Gareth Chisham, BAS) Now feed into EISCAT scheduling (Ian McCrea, RAL) Uses publicly available data PGP files MSP(Cluster)/MSOP(DSP) Footprint trace using T96 model P SW =2nPa, D ST =0 nT IMF B Y = IMF B Z =0 nT

If you are also interested in considering the corresponding orbit/footprint for the equatorial DoubleStar spacecraft (known as TC1) then the directory "all_pgp_orbit_plots" on the same machine contains new style plots showing DoubleStar and Cluster (1 gzipped ps file= 1 month). Daily jpg plots of the same format can be found in "daily_orbit_plots" (the new style orbit plots in.gif format 1 file = 1 day) and "daily_footprint_plots" (the new style footprint plots in.gif format 1 file = 1 day). Suggestions for November 2005 conjunctions by the end of August please! Best wishes, Jim Wild and Gareth Chisham (SuperDARN spacecraft working group)
