NEOs Close Recent Approach Passed and Present Approach - Meteors, Asteroids and Bolides; Oh! My! Leap for Leap Year!!! 23FEB2012
Debris from passing NEO asteroids ((2012 DF4), (2012 DX), (2012 DZ), (2011 CP4), (2012 DY), (2012 CS46)) will continue through the end of FEB2012.
Get out and WATCH if you haven`t already been doing so!  Video cameras, security cameras, and Allsky cameras READY?  Get the word out to look up.

Leap Year 2012; Lemming. http://en.wikipedia.org/wiki/Lemming
"Misconceptions about lemmings go back many centuries. In the 1530s, the geographer Zeigler of Strasbourg proposed the theory that the creatures fell out of the sky during stormy weather (also featured in the folklore of the Inupiat/Yupik at Norton Sound), and then died suddenly when the grass grew in spring.[6] This description was contradicted by the natural historian Ole Worm, who accepted that the lemmings could fall out of the sky but claimed that they had been brought over by the wind rather than created by spontaneous generation. It was Worm who first published dissections of a lemming, which showed that they are anatomically similar to most other rodents, and the work of Carl Linnaeus proved that the animals had a natural origin.[7][8]..."
