Year = 1998 Month = April Day = 29 Day-of-year = 119 Site = Poker Flat Sunrise = 13:26 Sunset = 06:07 Moonrise = 15:49 Moonset = 09:33 Moon_age = 2 Aurora = Very Quiet - Faint arcs visible at times, far to the north Cloud = Overcast all night Magnetometer = Quiet ASC = Summer season, did not run MSP = Ran all night but several channels failed VHF_radar = Good data coverage for the entire 24 hours Electrojet = Unknown SDI = Ran all night, poor data Bomem = No data MSG = No data Trailer = No data UW_FPI = Ran all night, fair data Stratosperic_lidar = Unknown Rayleigh_lidar = Unknown Resonance_lidar = Unknown Ebert = No data Comments = Entry at 14:40 UT, MC. Too much cloud and too little signal for good SDI data. Winds are obviously contaminated by the cloud. Nevertheless, you can at least see that there was westward flow before midnight, and that the wind probably turned eastward around magnetic midnight - though the data are pretty ratty. Temperatures may be ok - its hard to tell. They are slightly warmer than I'd expect (around 1100K). Last day of the UARC campaign. Very quiet geophysically, very shabby optically!
