Re: (meteorobs) ORIONID Oct. 4, 1999 La Crescenta, CA
Hi Sid,
Thanks for sharing your report. I noticed that you listed this meteor as
medium speed having a angular velocity of 45 degrees per second.
Actually the maximum angular velocity is 38 degrees per second so a
meteor of medium speed would actually possess a speed near 10 degrees
per second.
Most of your meteor velocities would lie at 10 degrees per second or
slower. Most swift meteors lie between 10 & 20 degrees per second. Very
few meteors exceed 20 degrees per second.
I hope this helps!
