The authors study Viking auroral images in the UV Lyman, Birge, Hopfield wavelength range for correlation of dayside auroral bright spots with various solar wind parameters. Such bright spots are seen primarily in the 1400 - 1600 MLT afternoon period, as one to four spots simultaneously, and commonly correlate with high solar wind speed, low solar wind density, radial interplanetary magnetic field. They show no correlation with solar wind pressure, B{sub z}, or B{sub x}.
