First Week of March Meteors

The first week of March continues February’s trend of low meteor rates and no major shower activity. Unfortunately this will be the case thorough most of April.

Bob’s notes …

Feb 28/Mar 1: “Another perfectly clear night with good activity. Two more Gamma Normids were recorded tonight. Leo and Ophiuchus continue to see a lot of meteor activity.”

Mar 1/2: “Another perfectly clear night with slightly less activity than last night. Occasional thin cirrus clouds could have reduced the counts tonight. Two more Gamma Normids were recorded tonight. The Antihelion radiant was more active than usual with 5 members. There were three areas in Ophiuchus that presented possible radiants. None had more than four meteors and they were not particularly sharp so these are most likely sporadic alignments.”

Mar 4/5: “The last two nights were lost to clouds. Tonight was perfectly clear night but rates were down significantly from the first two sessions this month. Two more Gamma Normids were recorded tonight. The first of these was very bright with an estimated magnitude near -3. It shot northward and ended near the handle of the Big Dipper. Plots revealed nothing of note tonight.”

Mar 5/6: “It was mostly clear tonight but with occasional cirrus and mid-level clouds. Overall activity was somewhat quiet but the Gamma Normids and Antihelion were active compared to the sporadic counts. There was a tight radiant in eastern Ophiuchus that produced four of the fifteen spordic meteors recorded tonight. It was not close to any bright star but located directly between Beta and Eta Ophiuchi.”
