Year = 1998 Month = November Day = 12 Day-of-year = 316 Site = Poker Flat Sunrise = 18:18 Sunset = 00:49 Moonrise = 09:25 Moonset = 00:21 Moon_age = 22 Aurora = Very Quiet - Faint arcs visible at times, far to the north Cloud = Clear early, overcast later Magnetometer = Very quiet ASC = Unknown 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) SDI = Ran all night, good data Bomem = No data MSG = No data Trailer = No data UW_FPI = Unknown CRL_NF_FPI = Unknown CRL_AS_FPI = Unknown Stratosperic_lidar = Unknown Rayleigh_lidar = Unknown Resonance_lidar = Unknown Ebert = No data Comments = A quiet night, and SDI winds reflect this. Some shear associated (presumably) with the dusk convection cell is resolved pre-midnight, around 10 UT. Winds are a little ratty toward the end, due to a combination of thin cloud and scattered moonlight. MC 12-Nov-1998.
