Special Time notes:

Note A: ARASE - This is a spacecraft working group request to support the
ARASE/ERG mission. The radars highlighted in the square brackets for each
interval should run interleaved_normalscan (a full scan of at least 16
beams with a non-sequential manner that interleaves the beam number, with a
scan time of 1-min). All other radars should run a 'normal' 1-min common
time mode e.g., normalscan. Footprint plots can be found at
https://ergsc.isee.nagoya-u.ac.jp/cef/orbit_ergsd.cgi .

Note B: THEMISSCAN - This is a spacecraft working group request to support
the MMS mission. All radars should run themisscan during this interval.
This mode has a camping beam which is sounded on every 6 seconds. The
scanning scheme is such that the field of view scan is interleaved with the
camping beam. The PIs/operators are welcome to adapt the mode for the
geometry for any conjunctions as they see fit (e.g., by changing the
camping beam) - footprint plots can be found at
http://www.southampton.ac.uk/~rcf2c13/footprints/ .

Note C: ST-APOG - This is a spacecraft working group request to support Van
Allen Probes (VAP - formerly RBSP) observations. The radars highlighted in
the square brackets for each interval should run rbspscan (a full scan of
at least 16 beams with an interleaved mini-scan of 3 beams, with a scan
time of 2-min). All other radars should run a 'normal' 1-min common time
mode e.g., normalscan. The PIs/operators are welcome to adapt the mode to
best fit the geometry of the conjunctions (e.g., by adapting the range
gates) - VAP footprint plots can be found at
