A short-duration activity outburst of the alpha-Monocerotids has been observed on November 22, 1995, between 1h15m and 1h45m UT. The highest EZHR occurred in the 10-minute interval 1h25m-1h35m UT and reached 350+-40. Higher EZHRs can be derived from shorter intervals. The peak time derived from the available data is 1995 November 22, 1h28m+-5m UT, or lambda=239.321+-0.004 degrees (2000.0). The FWHM of the peak as derived from the 10-minute intervals amounts to 0.019 degrees in solar longitude or 27 minutes. The population index r has been found to be r=2.51+-0.05. Assuming an atmospheric entry velocity v_infty=60 km/s, the peak number density is 50 times 10^-9 km^-3. This is comparable to the 1991 Perseid peak figures.
