As mentioned in Laura's updates about comet Elenin, there will be a Sun-new Moon-Earth-Elenin alignment on September 27. When the moon is new, it blocks the electron stream hitting the earth from the Sun, and when it moves out of the way, the earth receives a blast of solar energy, compressing the ionosphere and producing storms. As this will be hurricane season, it could produce some storm activity, as happened in 1999 with the Sun-Venus-Earth-Lee alignment which produced Hurricane Floyd (and which McCanney predicted). The alignment occurred on September 6, Floyd formed on the 8th and the new moon was the 9th. The inclusion of Venus most likely increased the energy hitting earth, so, barring any unseen factors, hopefully things aren't as bad this time around.
