Miscellaneous Results (from other regions)

 

 

Reports without links are Incomplete - awaiting further observations.

(m) indicates a Miss observation within an event with at least 1 positive observation

*Profiles provided here are preliminary.

Profiles shown for the "only 1+" events are for observer feedback only.

Asteroid profiles only show the line of sight view at the time of the occultation.

The true size/shape of an asteroid in 3-dimensions cannot be determined from a single occultation.

Dave Herald should be contacted for "official" profile information.

Determining the Profile of an asteroid from a limited number of observations can lead to misrepresentations.
