• Orbits and footprints of Geotail (GT), Cluster (reference spacecraft) (CL), Double Star TC1-TC2 (T1-T2), THEMIS P1-P5 (P1-P5), Reimei (RM), and FAST (FA) are plotted in black, blue, green, yellow to red, violet, and green, respectively; RM and FA are shown only in 2 hour plots.
• Geocentric solar magnetospheric (GSM) coordinates are used for the magnetosphere; altitude adjusted corrected geomagnetic (AACGM) coordinates are used for spacecraft footprints and ground-based instruments.
• The dashed lines from the pole in the upper panels indicate midnight meridians at different universal times.
• Light-gray solid fans indicate fields of view of SuperDARN radars at an altitude of 400 km. Dark-gray solid circles with a white dot indicate fields of view of OMTI (Resolute Bay and Athabasca) and NIPR (Syowa and South Pole) cameras at an altitude of ~250 km; open circles indicate fields of veiw of THEMIS cameras. Blue dots indicate the locations of the EISCAT radars (Tromsoe and ESR). These fans, circles, and dots are drawn when the operations are carried out. For example, the operation of the OMTI Resolute Bay camera started on 10 January 2005.
• Input parameters for the Tsyganenko 96 model are shown in the bottom left-hand corner of the upper right panel: the solar wind dynamic pressure = 2 nPa, Dst=0, and IMF By=Bz=0 for 1 day plots, and the 2-hour averaged OMNI2 data for 2 hour plots. When the Dst index is not available in the OMNI2 data, Dst=0 is used and indicated in red. The altitude of spacecraft footprints is 120 km.
• Predictive orbit data are indicated by "P" at the end of the name of spacecraft.
