We compute the three-point temperature correlation function of the COB
E Differential Microwave Radiometer (DMR) 2 year sky maps to search fo
r evidence of non-Gaussian temperature fluctuations. We detect three-p
oint correlations in our sky with a substantially higher signal-to-noi
se ratio than from the first-year data. However, the magnitude of the
signal is consistent with the level of cosmic variance expected from G
aussian fluctuations, even when the low-order multipole moments, up to
l = 9, are filtered from the data. These results do not strongly cons
train most existing models of structure formation, but the absence of
intrinsic three-point correlations on large angular scales is an impor
tant consistency test for such models.
