UPDATE MAY 25, 2006:
According to informed sources, contacts in the American intelligence services confirm the existence of a time window of 48 hours, centered on May 25th at midnight GMT, for the impact a comet fragment south of the Azores.
This information corroborates information of an evacuation exercise of the U.S. Congress to occur later in the day of May 25th, information which reached us this morning.
As a measure of precaution, I suggest the authorities do the utmost to protect the populations of the Atlantic coastlines.
