Announcing Comet C/2002 T7 (LINEAR)

Explanation: A newly discovered comet may outshine most stars in the sky by May. Designated Comet C/2002 T7 (LINEAR) , the comet was discovered in 2002 October by project LINEAR . Many reports already place the comet as brighter than magnitude 7, meaning that it can now be seen with binoculars. Reports also indicate the comet already has a visible tail nearly the length of a full Moon . Since predicting the future brightness of comets is a very tricky business , there remains the possibility that T7 might never become visible to the unaided eye. Alternatively, another comet, C/2001 Q4 (NEAT) , may also reach naked eye visibility at nearly the same time, making 2004 April and May two of the busiest bright-comet months in centuries. Comet T7 can be seen on the above right on January 20, while an airplane trail is visible on the left.
