Oct 24/25/26 Meteors

After peaking in intensity last week, the Orionids are slowly winding down for 2009. Rates are about half to a third of what they were at the peak. This is true for both video observers and visual observers.

Bob’s notes for the past 2 nights : “Listed below is data from the past 3 nights obtained from home. On the 24th skies clouded up after only 2 hours of observing. The remaining two nights were mostly clear except for some scattered cirrus.”

    Interesting story developing about a “mystery” object that’s been picked up by several observatories looking for near Earth objects… it seems to be on a 31 day Earth orbit and will next fly-by at approx 0.2 lunar distance on 29th October.

    Object designation currently: 9U01FF6

      Hi Chris,

      Yep, I’m watching this one closely. It’ll probably end up being something man-made (which as a space program buff, is still cool) but a natural object can’t be ruled out yet. The orbit dynamics people will be able to tell when it is re-observed in a few weeks.

      There has been a few cases of man-made Apollo era hardware returning to Earth after spending decades in heliocentric orbit. Then there was the case of 6R9DB10 = 2006 RH120, a ~2 meter asteroid that was temporarily captured into a pseudo-Earth for a year or so.

      Cool stuff…
      – Carl
