The peak of the Orionids is here. Last nights numbers were comparable to what was seen last year on Oct 20 and 21 UT. This suggests that the Orionids are at least as strong (ZHR = 30-40 meteors per hour) as they were last year.

An interesting meteor shower - the "Orionids" meteor shower - is now on display in the sky.
Here in the Philippines, however, it is being overshadowed by news about typhoons.
Even the chief of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) appeared to have forgotten about the annual meteor shower seen from Oct. 17-25, with its traditional peak nights on the 21st and the 22nd.

Orionids Meteor Shower Starts This Weekend
Earth is currently ploughing through space debris left behind by a visitor that last swung by during the Reagan Administration.
Spawned by Halley's comet, which last buzzed the planet in 1986, tiny space rocks are the seeds of the annual Orionid meteor shower.
Beginning Friday, sky-watchers should see some of the year's first Orionids. And thanks to a moonless midnight sky, the shooting stars should be fairly simple to spot.

Ed ~ Just an after note about the "Meteor Mania" program at Kitt Peak; the cost is ~ $35.   This doesn't sound like a good deal to me: One enjoyable aspect to meteor watching is that it is free.

The Orionid Meteor Shower, consisting of fine meteoric debris, collides head on as we speed round the Sun.  The Orionids, leftovers from the passing of Halley's Comet, can be one of the more prolific annual showers although numbers have been erratic in the past.
With these tiny particles encountering our atmosphere at great speed fast moving meteors are produced with a good proportion leaving persistent trails.  Average brightness is around the same as the stars in the Plough (magnitude 2/3) with some much brighter and if exhibiting long trails these meteors can appear quite striking.
