Mar 1/2 Meteors

A sprinkle of sporadic meteors continue. A possible single Gamma Normid was detected over Tucson last night.

From Bob’s notes for the night of Feb 28/Mar 1: “The sky was clear but hazy all night. Still no activity from the Delta Leonids to report.”

Bob’s note for the night of Mar 2/3:”Thin cirrus was present all night long yet counts were similar to the previous night.”

    1. Hi Anangeli,

      I think you are talking about the small asteroid 2009 DD45. This asteroid passed ~40,000 miles above the Pacific Ocean on March 2. It was the 3rd closest (known) approach of an asteroid to Earth. The best estimate is that it was ~60 feet across. That’s not big enough to do world-wide damage but you wouldn’t want to live near where it hit.

      There is a nice article from Sky and Telescope here:

      As well as a post from my blog:

      Thanks for writing,
      – Carl
