Rates were down from the previous night. Bob detected a decrease in Sporadics while I saw a decrease in Orionids. We’ll see how things go tonight.
We are still ~5 or 6 days from maximum so the best of the Orionids is yet to come. According to the IMO’s Live ZHR graph, the Orionids are now producing ~10 meteors per hour for visual observers under dark skies during the last few hours of the night. We can expect that rate to climb to a max of anywhere from 30 to 70 per hour.
From Bob: “For some odd reason the sporadic rates were down nearly 50% from yesterday. It was clear all night long so it was most likely just a quirk and rates should recover tomorrow.”
