A night after their peak the number of Quadrantids are down sharply. Amazingly the total number of meteors was up from a night ago as the number of Sporadics made up for the lack of Quadrantids.
Bob’s notes from the night of Jan 3/4 : “Thick high clouds delayed the start of recording tonight. It was mostly clear between 3 and 11 UT (7pm to 3am PST). After 11 UT, thick high clouds obscured the sky effectively ending observations for the night.”
