Meteor Showers

There are many minor meteor showers this month...
The northern Taurids and southern Taurids start to become active about October 1st, but do not reach maximums until early November. Both have fairly slow meteors, with the northern Taurids velocity at 29 km per second, and the southern at 27 km per second. At maximum in November, both showers will peak at about ZHR rates of 5 meteors per hour. These meteors are part of the Taurid stream which in turn has been associated with Comet Encke.
Late Orionid rates typically continue until about November 7, long after their October peak, for post-midnight observers, but little is likely to be seen of them, thanks to the waning gibbous to last quarter Moon. In early November their radiant lies a few degrees east of the second magnitude star Geminorum.
The Leonid Meteor Shower is one of the better meteor showers to observe, producing an average of 60 meteors per hour at their peak. You can listen to them by tuning to the 67 MHz meteor radar in Roswell, NM.

Shower Activity Period Maximum Radiant Velocity ZHR


Date R.A. Dec. km/s
Northern Taurids Oct 1 - Nov November 3.2h 17.5° 29km/s 5
Southern Taurids Oct 1 - Nov November

27km/s 5
Leonids Nov 17-21 Nov 17 - 19

The Celtic new year begins on the 1st

The holiday was called Samhain (Sah-ween). The date marked the beginning of winter. The Celts believed that at the time of Samhain, more so than any other time of the year, the ghosts of the dead were able to mingle with the living, because at Samhain the souls of those who had died during the year travelled into the other world. People gathered to sacrifice animals, fruits, and vegetables. They also lit bonfires in honour of the dead, to aid them on their journey.

Here are a few deepsky objects to look out for:

In Aquila , The Ghost of the Moon Nebula
In Cetus, NGC246 called The Skull Nebula.
In Bootes (abbreviated BOO), you may find The Spider Galaxy, NGC5829 .

Leonid Meteor Shower. The Leonids is one of the better meteor showers to observe, producing an average of 60 meteors per hour at their peak. The shower itself has a cyclic peak year every 33 years where hundreds of meteors can be seen each hour. The last of these showers occurred in 2001. The shower peaks this year on November 19. Look for the shower radiating from the constellation Leo after midnight.

The Pleiades
In the evening sky youll see the wonderful gem of an open cluster rising in the East. As Tennyson said "The Pleiads , rising thro' the mellow shade, Glitter like a swarm of fireflies Tangled in a silver braid...".
Nearly every culture mentions the Pleiades in some respect. Chinese writings appear to mention it from 2357 BC. American Indian folklore of the Kiowa talks of the "Seven Maidens" who where protected from giant bears by their placement in the skies. To the Japanese, they are called Subaru.
