  The two-point correlation function, $\xi$, of Lyman-alpha forest is found to
be large, $\xi = 1.8^{+1.6}_{-1.2}$, > 90% confidence level, on the scale of
250-500 km/s for a sample of absorbers (0 < z < 1.3) assembled from HST Key
Project Observations. This correlation function is stronger than at high
redshift (z > 1.7) where $\xi \approx 0.2$ for velocities > 250 km/s.
