Fireball reporting
I have added a section on fireball reporting to my web site at:
http://members.shaw.ca/epmajden/index.htm This includes hyper links to Fireball Report Forms and also a link to the video of the Peekskill N.Y. fireball which dropped a meteorite which was recovered after impacting the back of a car. Dr. Jeremy N. Tatum provided a paper which describes what is needed for serious analysis of a fireball drop zone. He insists on instrumental measurements obtained by an in situ interview of the witness of the fireball by a trained investigator. Predicting a drop zone is difficult even with accurate measurements so he won't attempt doing the math until he has reliable confirmed measurements. Even with photographic methods this is not as precise as one may think. Anyone predicting a drop zone without accurate measurements is just kidding him or her self. Hopefully search engines will find my site and list it under Meteor Fireball Reporting. Dr. Martin Beech has written an interesting pdf paper pointing out some of the difficulties of meteorite recovery. See: hyperion.cc.uregina.ca/~astro/MIAC/Dec_ret.pdf Hopefully this will encourage observers of fireballs to fill out reports and provide enough information so the person can be contacted in case the researcher needs better information.
