While ISON is approaching the Sun in the next few days and is currently invisible, Comet C/2013 Lovejoy is easily observable in the northern emisphere before the dawn, in the constellation of Canes Venatici,
This picture (6 minutes exposure through a 10mm diameter astrograph), was taken on November 24 at 4:00 UTC. Despite the Moon was very close to it, the comet appears beautiful, showing nice details of its tail.
Being at around 145 million km from the Sun, Lovejoy has just crossed Earth’s orbit.
