COMETS COMETS
DEEP SKY DEEP SKY
Pan-STARRS discovered a 20th magnitude comet on 2013 December 4. There were pre- discovery images from the Mt Lemmon Survey taken on November 29. The comet brightened quite rapidly, generating many reports of an outburst, but these seemed premature as there was no substantial deviation away from the mean light curve (at other times there were as many observations below the mean curve, yet there were few reports that it was disintegrating).  At perihelion it will be visible from the Southern Hemisphere, when it may be an easy binocular or naked eye object.
