Jan 21/22 to 30/31 Meteors

After some downtime due to computer issues and bad weather, Bob’s cameras are once again capturing meteors. Bob’s nightly summary give a great synopsis of meteor activity during the last week of January so I’ll let him do the talking…

Jan 21/22 – “After a long delay due to cloudy weather and computer problems, I am back in business with a new computer and hopefully some clear skies. This session was good despite the bright waning gibbous moon. The December Leonis Minorids were well represented but the Gamma Ursid Minorids did not produce any activity.”

Jan 24/25 – “The sky was clear the entire night. I had somewhat of a late start as I was busy at sunset plus I had to tweak some settings on my new computer to get it to work properly. Meteor totals are close to what is to be expected for this setup in late January.”

Jan 25/26 – “The sky was clear the entire night. I still started about 30 minutes late due to computer problems. Meteor totals for the night are near normal but the individual shower totals are high. The 27 sporadics are low for an entire night for this setup. The ANT’s and the DLM’s produced 6 and 4 meteors respectively, which is higher than normal this time of year.”

Jan 26/27 – “The sky was clear the entire night. It was another good night for shower activity with 6 Antihelion and 3 December Leonis Minorids being recorded.”

Jan 27/28 – “The sky was clear the entire night. Activity was less than the previous few nights. Surprisingly 3 Alpha Centaurids were recorded on the first night of their activity period.”

Jan 28/29 – “This was the last of a nice clear stretch observed in extreme southwestern CA. The sky was clear all night long. A waning crescent moon rose late in the session but did not compromise observations. Rates were good with 41 meteors being recorded. The Alpha Centaurids continue to be strong with 4 members being recorded during the last few hours of the night. No December Leonis Minorids were recorded.”
