Feb 14/15 to 22/23 Meteors

It’s been an amazing run the past few months. From the end of September until the very last day of 2010, the nights in Tucson were clear enough to allow a few meteors to be detected. Even January was clear 30 out of 31 nights. February started off just as clear but last week the clouds finally won out with 4 whole nights being lost to bad weather. It wouldn’t have been so bad if the clouds had actually brought more than a measly 0.05″ of rain. Perhaps we’ll do better with the storm forecast to hit this weekend.

Bob’s notes …

Feb 21/22: “The sky was clear at dusk but clouds quickly formed during the early evening hours, covering the entire sky by 2200 (10pm). No meteor activity was recorded after this time.”

Feb 20/21: “We lost 5 nights due to recent storms that affected both San Diego and Tucson. This night had lots of post-frontal cirrus and a bright moon, which accounted for the low counts.”

Feb 14/15: “The forecast was for cloudy skies but the sky was clear the entire night. Despite the bright moon that was above the horizon most of the night, a decent total of 22 meteors were recorded. The constellation of Leo was once again the center of attention with 3 Antihelion and several sporadic meteors. Our weather forecast calls for clouds and rain for the next week. It has been a nice run of 15 nights in a row with observations. Not bad for this area in February! Hopefully we can return to better weather later in the month and on into March.”
