THEMIS Workshop
December, 2005
SuperDARNNorthern Hemisphere
Orange and red-shaded radar fields are operational.
Mustard and pink radar fields are under develop-ment or planned.
Rankin Inlet will be opera-tional by Spring 2006.
Finland East and Hokkaido may be operational by Fall 2006.
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.

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

November 2005 conjunctions:
------------------------------------
We would be grateful if you would start to consider the equivalent operations for November 2005. Cluster orbit and footprint plots can be found via anonymous FTP at...
machine: cluster.ion.le.ac.uk
directory: c1_pgp_orbit_plots
...which contains the Cluster orbit/footprint plots (Cluster 1 only, 1 gzipped ps file= 1 month).
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)
