Another example of improved computing making the impossible into the practical and routine

A decade ago, the peak intensities of many meteor showers were difficult to predict and were often just guesstimates. Meteor storms were predicted, and observers saw nothing. No one was looking, and surprise showers appeared. That is why the Aurigid meteor shower is known to have been observed by only three people before yesterday. (I woke mom up at 1:20, and she saw one in a few minutes even though it was nearly completely overcast!)

Improved computing now allows much better prediction of meteoroid streams. Models are so good that the predicted peak of the Aurigids was 4:33 AM PDT, and the actual peak was 4:15 AM; the predicted peak rate was right on target. A decade ago, you would have gotten tentative guesses as to whether or not one would see anything at all.
