Every night seems to see at least one minor meteor show come and go. It’s been a little hard to keep up with them. Most of the showers are very minor, perhaps producing a meteor per hour at most. The majority of them have only been identified in the past few years in video and radar data.
The most important shower to become active over the past few nights is the Geminids. Though this shower is currently only producing a meteor or two per hour activity will pick up next week. By the time the shower peaks on the night of December 13/14 it will be producing between 100 and 150 meteors per hour for observers under dark skies.
It looks like the rains are finally coming to the southwest US. The forecast is for a series of storms to hit the area next week. Hopefully it will be clear for the Geminid peak. Speaking of rain, my zenith pointing camera is still out of commission due to condensation in its lens. I have ordered a new lens which will hopefully show up sometime this week.
Bob’ notes for the night of Dec 3/4 : “After two nights of clouds, the skies cleared enough for video observations. The bright gibbous moon and hazy conditions were not ideal. It was surprising that no northern Taurids were recorded tonight. Even though they are near the end of their activity period, the antihelion meteors included in the NTA count should have amounted to something.”
… for the night of Dec 4/5 : “Several layers of clouds moved in overnight greatly reducing the number of meteors recorded.
