Especially during the Galaxy's early history, when the metallicity of the ISM was low, the spallation of protons and alpha particles onto CNO nuclei cannot account for as much B as we observe unless the CR flux was sufficiently higher to compensate. It is possible that the gamma rays recently detected from the Orion Nebula region are the signature of spallation by energetic C and O nuclei. Nevertheless, B, Be, and Fe data alone give the strongest evidence of the importance of spallation by C and O for producing light elements. My plan to lead a tour to the June 2001 total eclipse in Africa on the Concorde supersonic jet has been cancelled. Chasing solar eclipses, such as this one in the Galapagos, and the northern lights.

The North Pole. I lead educational vacations here to experience the northern lights and native culture. Living in an igloo is something we do for fun. Using two twin otter aircraft and a fuel cache, we travelled to the North Pole, Beechey Island, and on to Thule, Greenland. Beechey Island is where the famous Franklin expedition vanished while looking for the Northwest Passage last century.
