Europe on dayside, North America on nightside 2. 2016 Jun 29 ( 2 mo): Apogees around 15:30UT (THEMIS 12MLT / MMS 24MLT, Phase 1x). Southern winter. South Pole on dayside, Australia on nightside 3. 2017 Jan 12 ( 2 mo): Apogees around 6UT (MMS 12MLT, Phase 2a / THEMIS 24MLT). Northern winter. Europe on dayside, North America on nightside 4. 2017 Jul 22 ( 2 mo): Apogees around 15:30UT (THEMIS 12MLT / MMS 24MLT, Phase 2b). Southern winter.

Expected data—Dayside Dayside auroral brightening/Reconn ection Fast flow Polar cap/Lobe Nightside auroral oval MMS DMSP (ARTEMIS) THEMIS RBSP Background: Real imager and radar data. Satellites would detect the source and transport of the dayside/nightside transients. Near magnetopause [Turner et al., 2013] 6 |B| Ti Vi Ion Ele N V Low-altitude [Nishimura et al., 2014] 12MLT 24MLT

The proposed coordination will maximize the use of Heliophysics System Observatory (HSO), and will provide opportunities for global space-ground observations simultaneously. This will open a new door to connect dayside, polar cap and nightside phenomena that have traditionally been discussed separately. e.g., Reconnection, Fast flow channels, Auroral brightening (PMAF/PBI) Intense collaborations between space and ground communities are essential to make this campaign successful. If we missed any key groups or instruments, please let us know. Teams we have contacted so far; Satellite: THEMIS/ARTEMIS, MMS, RBSP, Geotail, ERG, WIND, DMSP, SWARM Imager: NORSTAR, OMTI, AGO; Svalbard, Alaska, South Pole, McMurdo, Syowa Radar: SuperDARN, AMISR, EISCAT, Sonde Ground mag: ULTIMA, CARISMA TEC, VLF, Riometer Summary 8
