Don't you recall Les' post from a few days ago?

Now bear in mind that asteroid was big enough and bright enough that it could have been seen with a backyard telescope...and it was not discovered until six days before it reached its minimum distance to Earth...Hmmm...

Big sky...not enough eyes.

We got a few close shaves coming in the next 80 years or so.

I don't think I can wait THAT long for a BK.

Current Meteor Activity Outlook September 1-7, 2000

The Sporadic rates for the Northern Hemisphere are nearing their annual maximum. Under the good conditions presented this upcoming week I would expect one would see 10-15 random meteors per hour from rural sites with little light pollution. This does not include the expected 5 or so meteors per hour from the apex sources so activity can be quite satisfying under truly dark skies this time of year in the Northern Hemisphere.

How frequently do meteorite falls occur?

Our best estimates of the total incoming meteoroid flux indicate that about
10 to 50 meteorite dropping events occur over the earth each day. It should
be remembered, however, that 2/3 of these events will occur over ocean,
while another 1/4 or so will occur over very uninhabited land areas,
leaving only about 2 to 12 events each day with the potential for discovery
by people. Half of these again occur on the night side of the earth, with
even less chance of being noticed. Due to the combination of all of these
factors, only a handful of witnessed meteorite falls occur Each year.

As an order of magnitude estimation, each square kilometer of the earth's
surface should collect 1 meteorite fall about once every 50,000 years, on
the average. If this area is increased to 1 square mile, this time period
becomes about 20,000 years between falls.
