Year = 1999 Month = October Day = 08 Day-of-year = 281 Site = Poker Flat Sunrise = 16:21 Sunset = 02:54 Moonrise = 14:51 Moonset = 03:20 Moon_age = 28 Aurora = Active - One or more breakups occurred, with bright aurora often south of zenith Cloud = Overcast all night Magnetometer = Disturbed ASC = Long moondown, ran OK MSP = No data, did not run VHF_radar = Good data coverage for the entire 24 hours Electrojet = Good data coverage from real-time calculations SDI = Ran all night, poor 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 = Unknown Comments = Cloudy all night, though I could make out a few auroral arcs through the cloud at times - enough to assess the aurora as "active", at least at those times. SDI data are pretty lousy. MC, 12-Oct-1999.
