This is a big catch-up post. The fall months usually see the highest meteor rates of the year and this year is no exception. Even though the Orionids are 2 weeks past their peak they are still producing more meteors per hour than any other currently active shower. This should change this week as the Orionids move towards inactivity. The 2 branches of the Taurid stream are nearing their maximum and will produce a consistent, though minor, contribution to November’s meteor rates. Surprisingly, the Beta Cancrids are still doing well which isn’t bad for a minor shower that we know little about. The nearly Full Moon has become a problem and will suppress meteor rates for the rest of the week.
Bob’s notes for the night of Oct 28/29 : “There was a thin veil of cirrus throughout the night that reduced the number of meteors recorded. The waxing gibbous further brightened the sky while it was above the horizon. Nothing notable in the shower numbers seen last night.”
Oct 29/30 : “The thin high clouds continued all night long again. Rates were similar to the previous night.”
Oct 30/31 : “The thin high clouds finally moved out of the area leaving pristine skies. A bright gibbous moon had less effect under the transparent conditions.”
Oct 31/Nov 1 and Nov 1/2 : “Clear skies and a bright moon were present both nights. Nothing notable was observed except for a few bright meteors.”
Nov 2/3 : “There were occasional high clouds last night which seemed to have affected the meteor rates more than the full moon.”
