The Alpha Monocerotids or Monocerotids of November is a meteor swarm with the international acronym AMO, not to be confused with the Monocerotids of December, international acronym MON. The swarm is visible from 15 to 25 November of every year; its peak occurs on 21 or 22 November. The speed of its meteors is 65 km/s. Normally it has a low ZHR but on some occasions it origins remarkable meteor rains, that have the characteristic to last less than an hour: such type of rains, named outburst, have been observed in 1925, 1935, 1985 and 1995. The outburst of 1995 has allowed to exactly determine the radiant of the swarm and the solar longitude of its peak beyond confirming the effective brevity of outburst of the Alpha Monocerotids, less than an hour. The parent body, probably a long-period comet, is unknown.
