Re: (meteorobs) Re: [IMO-News] ZHR's Nov. 17/18 from Safford (AZ)



Roger,

  That's a very low rate. My rate peaked twice - 10:46 a spike of 60/min 
followed by 57/min and later a 10-minute interval centered at 11:05UT with top 
rate 64/min and a constant rate of over 50/min. LM was 6.3-6.4 at the time. Oh 
yes, there was also a constant F factor from 10% to 20% by cirrus clouds.

I didn't post my summary on 'meteorobs' but I'll send it to anyone who'd like 
to take a look at it.

Clear skies!

Jure
