COMETS FOR THE VISUAL OBSERVER IN 2010

摘要

The list of short-period comets expected to become bright enough for visual observations during 2010 is fairly small,although three of these should be easily visible in small instruments and one may reach naked-eye brightness. Twolong-period comets that pass perihelion during 2010 (discovered by late Dec. 2009) also have the potential of reachingfaint naked-eye visibility; of course, many others yet to be discovered will undoubtedly be visually observable during2010.
