QUOTE: "...May 9th, as the sun was rising over Gdansk, Poland, an exploding fireball split the sky. Eye-witness Krzysztof Polakowski of the Polish Fireball Network describes it as a "magnitude -8 meteor" or 40 times brighter than Venus. Believe it or not, this shadow-casting fireball was ... nothing special. According to calculations done by Bill Cooke, head of NASA's Meteoroid Environment Office, magnitude -8 fireballs appear somewhere on Earth around three times a day. That's almost one hundred a month! Lesser fireballs occur even more often...They are caused mainly by random bits and pieces of asteroid and comet debris crashing into our atmosphere as Earth orbits the Sun...."
