(meteorobs) Large fireball frequency calculations - Needs updating

[Thomas Ashcraft]

For what it's worth :

The fireball frequency calculations that are referred at     
http://www.spaceweather.com/glossary/frequentfireballs.htm?PHPSESSID=27ojbhs2oliu6kadsjaj0gbhd3 

seem to me to be way underestimated.

"According to his calculations, fireballs as bright as Venus appear 
somewhere on Earth more than 100 times daily. Fireballs as bright as a 
quarter Moon occur once every ten days, and fireballs as bright as a 
full Moon once every five months."

My own camera system has captured four -13 magnitude events in the past 
year.

So with fresh data from the various all-sky fireball networks maybe 
these calculations can be updated to give a more accurate picture.
