Nov 9/10/11/12 Meteors
November 12, 2009 2 Comments
Rates appear lower than usual. The reason is the persistent cloud cover over the American southwest. The cirrus is thin enough that the brighter meteors have been visible.
The Taurids continue to produce a few video meteors a night. Surprisingly the Orionids still account for a sizable fraction of detected meteors. As for November’s main shower, the Leonids are still showing low activity. This will change by early next week.
Bob’ notes for the night of Nov 9/10 : “I was only able to record during the last two hours of the night. Still, I managed to record 21 meteors.”
Night of Nov 10/11 : “It was cloudy all night long with varying layers of high clouds. At times you could see some of the brightest stars but most of the night the sky was blank. Under these conditions only 12 meteors were recorded.”
Night of Nov 11/12 : “High clouds continue to stream over the San Diego area. There were stars visible at dusk but the skies worsened as the night progressed. I had to quit recording near 1:30am PST as the sky became totally overcast. At 4:45:51 (8:45:51) I recorded the brightest fireball yet captured by my camera. It was a member of the Southern Taurid shower with an estimated brightest near -10.”
Below is an image of the -10 magnitude Southern Taurid imaged by Bob over San Diego.
