Oct 22/23 Meteors

Orionid activity has not let up at all. Last night’s rates are comparable to the past 3 nights. The graph below presents the number of Orionids my 2 camera SALSA system detected throughout each night. Though there may have been sky brightness and transparency difference from night-to-night, the nights were clear when the Orionid radiant was above the horizon allowing for a realistic measurement of the night-to-night variability in activity. [Note, there were  clouds on the 19th so its numbers are probably too low.]


Visual reports to the IMO’s real-time page, still show activity varying between a ZHR of 25 and 45 meteors per hour. Some of the variation is undoubtably due to different observers and observing conditions, but some of the variation may also be real as the Earth encounters dust streams of different intensities. Rates should start falling by tonight.

Bob’s report from the Mojave : “My last night from the Mojave Desert was plagued by cirrus clouds and equipment problems. Dead batteries limited my video recording to only two hours. Luckily this two hour period was cloud free.”

  1. Thank you Carl, for your daily updates! I really looking forward to this results; very useful for my own visual observing work. Also many regards to Bob!
    Long trains,
