Amateur astronomers are monitoring a bright new comet easily detectable by backyard telescopes. Introducing, Comet SWAN25F:
"Newly-discovered Comet SWAN25F is brightening nicely as it approaches the sun," reports Mike Olason, who sends these pictures from Tucson, Arizona. "On the morning of April 6th, the comet was magnitude 8.4 with a bright green 3' wide coma and a thin tail that extended well beyond my field of view."
The comet is named after the SWAN camera onboard the Solar and Heliospheric Observatory (SOHO). Australian amateur astronomer Michael Mattiazzo noticed the comet in online images. SWAN is a special camera that maps hydrogen in the solar wind, which suggests this comet may be rich in the element.
