Recent Archived Strike Probabilities (Check here if you get a "busy signal": there may be a nearby city archived)

If you know the latitude and longitude of your location, you can make your own list of locations using a URL like http://www.solar.ifa.hawaii.edu/cgi-bin/StrikeProb?latitude=xx.xx&longitude=xx.xx&location=City+Name where you replace the xx.xx with the actual latitude and longitude in the format dd.mm (dd is degrees, mm is minutes; use a minus sign for south latitude and east longitude). The location is any text with a plus sign to represent a space. For example, http://www.solar.ifa.hawaii.edu/cgi-bin/StrikeProb?latitude=+31.33&longitude=-130.33&location=Kagoshima,+Japan gives the probabilities for Kagoshima, Japan.
