Several important dates are approaching. On March 5th, Comet Pan-STARRS makes its closest approach to Earth (1.1 AU), followed on March 10th by its closest approach to the sun (0.3 AU). As Comet Pan-STARRS passes the sun, solar glare might make it difficult to see even as the nucleus vaporizes and brightens. By March 12th and 13th, the comet will reappear in the sunset skies of the northern hemisphere not far from the crescent Moon; think photo-op! Light curves suggest that the comet's brightness will peak near 2nd magnitude, similar to the stars of the Big Dipper. Check the realtime comet gallery for the latest images.
