The ability of digital sky surveys to collect and store very large amounts of
data provides completely new ways to study the local universe. Perhaps one of
the most provocative observations reported with such tools is the asymmetry
between galaxies with clockwise and counterclockwise spin patterns. Here I use
$sim1.7cdot10^5$ spiral galaxies from SDSS and sort them by their spin
patterns (clockwise or counterclockwise) to identify and profile a possible
large-scale pattern of the distribution of galaxy spin patterns as observed
from Earth. The analysis shows asymmetry between the number of clockwise and
counterclockwise spiral galaxies imaged by SDSS, and a dipole axis. These
findings largely agree with previous reports using smaller datasets. The
probability of the differences between the number of galaxies to occur by
chance is (P<4*10^-9), and the probability of an asymmetry axis to occur by
mere chance is (P<1.4*10^-5).
