Minor Planet Center just issued a circular about new comet discovered by Pan-STARRS survey. Comet was designated as C/2011 L4 (PANSTARRS) and it may be a very bright comet on 2013! The orbit is not accurate, but it’s already clear that the new comet have closer perihelion  than the comet C/2010 X1 (Elenin) – about 0.36 AU.

The comet could reach magnitude 1-2 in April 2013. By the rough forecast, C/2011 L4 can be the Great Comet, and reach 0 magnitude or brighter. In March 2013, C/2011 L4 will be about 1 AU from the Earth. This is in 4 times distant than the comet Elenin.
