Magnetometer = Disturbed
ASC = Long moondown, ran OK
MSP = Ran all night on all channels
VHF_radar = Good data coverage for the entire 24 hours
Electrojet = Good data coverage from real-time calculations (typically 5 minute intervals)

Comments = Nice SDI data.  The first hour or so of wind data looks "messy" - but observing conditions were good at the time. I suspect the SDI was seeing the wind in transition between pressure gradient and ion-drag dominated flow.
