sumac, that's right. We had a good rain last night, then more sunshine. Unless we get more soon it won't matter ---Fall begins Friday.

....was flying over Canada, Africa and parts of the Pacific, Atlantic and Indian Oceans....NASA estimated that roughly 26 large pieces of the spacecraft would survive the re-entry process to be strewn over a 500-mile (804-kilometer) path. The largest piece of debris is expected to be approximately 300 pounds (136 kg), but it is still unconfirmed whether debris fell over land or water.

The Canadian NORAD Region (CANR) is headquartered with the 1 Canadian Air Division in Winnipeg, Manitoba.

...To foresee the paths of space junk so that collisions can be avoided, NASA developed one of the world's most sophisticated predictive models. Called Legend (for "low-Earth to geosynchronous environment debris"), the three-dimensional model simulates the routes of all trackable space objects and even factors in new debris from future crashes. To take uncertainty and randomness into account, hundreds of scenarios are generated using the Monte Carlo method, a set of algorithms that can calculate risk factors in a complex environment. With Legend, NASA scientists use the average of multiple simulations to estimate the number, size, and type of objects that will collide—and approximately how often. Unlike models used by the U.S. Strategic Command Joint Space Operations Center, which detects and tracks large objects and screens active satellites daily for possible collisions within 72 hours, Legend includes smaller fragments and looks far into the future.
