Nov 11/12 to 16/17 Meteors

The maximum for this year’s Leonids shower should have taken place late this morning a few hours after sunrise here in AZ. So based on last night’s results I have only one word to describe the Leonids maximum, at least video-wise, and that word is ‘yawn!’. When the SALSA3 camera picked up 8 Leonids back on the night of Nov 11/12 I got real excited about a good display for this year. As it turned out, none of the subsequent nights really did much better. Still except during dust trail crossing years, the Leonids only produce 10-20 meteors per hour. That’s 10-20 per hour if you live under very dark skies. For most of us living in light polluted areas, rates are more like 3-8 per hour. So to be honest, I never really understand why every year there are news stories (for instance, the Leonids are on the front page of Yahoo News right now) telling the public to see what is really just a good minor shower most years. It would be much better to wait a month for a real high rate shower like December’s Geminids.

Last night marked the 53rd consecutive night with a meteor detection by the SALSA3 camera. The current forecast calls for the slight possibility of rain this weekend so we’ll see if the streak can live on.
