Feb 5/6 to 9/10 Meteors

The usual low February rates continue. Well with the exception of the night of Feb 6/7 when SALSA3 caught twice as many meteors relative to the other nights. I should probably take another look at that data to make sure everything’s valid.

Below is Bob’s excellent nightly commentary to go with his observations:::

Jan 31/Feb 1 – “I lost two nights due to clouds and rain. The day of February 1st was partly cloudy but the sky had totally cleared by sunset. Unfortunately there were clouds off the coast which arrived after sunset preventing me from recording any activity prior to 10:20 PST. It remained clear until 00:20 when another patch of clouds obscured the sky. This lasted until 01:30, when it finally cleared for the remainder of the night. Although it was clear during the time the ACE radiant was above the horizon, no activity from that radiant was recorded this morning. Totals from the other sources of activity were compromised due to clouds.”

Feb 5/6 – “The weather conditions continue to deteriorate as a front passes to the north. The evening hours had patches of low clouds interfering with observations, especially between 6-8UT (10pm-12am PST). After 10UT (2am PST) the sky became completely overcast and observations were stopped. Only five meteors were recorded, nothing noteworthy.”

Feb 6/7 – “Contrary to the weather forecast, the sky remained clear the entire night. Despite the favorable conditions, meteor totals were unimpressive. We have lost the Alpha Centaurids from this site as the radiant does not now clear the southern horizon.”

Feb 7/8 – “Clouds were a problem tonight. The the sky was clear from dusk to 2000 (8pm PST). After 2000, clouds interfered with observing until 2300 (11pm PST), when skies cleared again. It remained clear until 0130, when it became totally overcast and remained that way the remainder of the night. Of the 14 meteors recorded, only one was associated with a shower (Antihelion). Plots did not reveal any other possible radiants.”
