"Elenin is not the end of the world"

Lots of hype on the net about this one  :)
but I looked it up in Astronomy magazine chatroom.. they sent me to:
seems that in August Elenin will only be visible from the southern hemisphere.
Its closest approach is about a month later.......It will have a brightness of about 5.9 magnitude, which will be a dim star to the unaided eye.  the comet  will have a diameter of 6 point 3 minutes of arc...... easily visible with a pair of binoculars, a quite nice featureless blob :) in a small telescope........
6 minutes of arc is 1/10th of a degree.....  hardly causing chaos in the streets   :)
not like the 70AD and 1910
 comet which was a flaming sword across the sky..........
