Oct 28/29 to Nov 5/6 Meteors and the Lack of Any ‘Hartley-ids’

The current streak of consecutive nights with a meteor detection is up to 41 now. And with no storm systems in the forecast the end of the streak is no where in sight.

Still some nights do experience clouds. Two nights ago, for example, was hampered by thin cirrus for the entire night which resulted in only half the number of expected meter detections.

The Orionids were still going strong back on Oct 28/29 but have declined to a light sprinkle. Luckily the Leonids are starting up and last night saw a total of 5 Leonids detected between the two cameras.

As mentioned in the previous Meteor posting, there has been talk in the media about a possible ‘Hartley-id’ meteor shower. These meteors would have been produced by Comet Hartley 2 which passed within 12 million miles of Earth 2 weeks ago. A quick look at my data over the past week shows no evidence of any shower radiating from the region around the constellation of Cygnus where the ‘Hartley-id’ radiant should be located. Other video meteor observers such as Chris Peterson (Colorado) and Garry Dymond (Newfoundland and Labrador) also detected no ‘Hartley-id’ activity. The lack of any observational evidence agrees with theoretical work done by Jeremie Vaubaillon which suggests that any meteors released by Hartley 2 over its past few returns would miss Earth by ~0.06 AU. This distance matches the current miss distance between the Earth’s and Hartley 2’s orbit.
