Re: (meteorobs) The Ursids



was watched by J. P. M. Prentice (Battisford, England). Excellent conditions on December 22 revealed only 1 Ursid in 1 hour and 43 minutes. The next morning, the sky was mostly cloudy, yet Prentice saw 8 Ursids during a 25 minute period when a small patch of the sky became clear. He estimated that the hourly rate must have then been about 20. Four plotted meteors revealed a radiant of alpha=207 degrees, delta=+74 degrees (1900).(11)


Gary,
    That 8 meteors in 25 minutes for small patch of sky (say 1/Xth) would be ZHR of 20, but for that small patch of sky?
    Actual ZHR ~ X.20 (Also depending on patch of sky location in relation to radiant)

    What do you think?

    Regards,
    Stuart.
