A HIGH-RESOLUTION MAP OF THE COSMIC MICROWAVE BACKGROUND AROUND THE NORTH CELESTIAL POLE

We present a Wiener-filtered map of the cosmic microwave background (C MB) fluctuations in a cap with 15 degrees diameter, centered at the no rth celestial pole. The map is based on the 1993-1995 data from the Sa skatoon (SK) experiment, with an angular resolution around 1 degrees i n the frequency range 27.6-44.1 GHz. The signal-to-noise ratio in the map is of order 2, and some individual hot and cold spots are signific ant at the 5 sigma level. The spatial features are found to be consist ent from year to year, which reinforces the conclusion that the SK res ults are not dominated by residual atmospheric contamination or other noncelestial signals.
