October Meteor Showers.—The month of October is usually one of the best periods for observing meteors. The moon will interfere this year in the early part of the month, but during the last half, observations may be satisfactorily made. The chief shower generally visible falls in the third week of the month, and is directed from a radiant point at 91°+15° on the north-eastern borders of Orion. There is also a strong shower which supplies slow and often brilliant meteors at about the same time as the Orionids, but this radiant in the eastern region of Aries at 42° +21° appears to be visible for a long period, and is also seen in the months of November and December. The Taurids often form a conspicuous display towards the end of October, but they are generally more abundant in November than at any other time of the year. The latter shower yields meteors very similar to the Arietids, and fireballs are frequently intermingled with the smaller members of the stream. The chief radiant is at 64° + 22°; it is difficult to define the date of maximum, but it usually occurs between November 20 and 23.
