In end of Jan 2004, the comet 2002T7 LINEAR was positioned around the boundary of Pisces and Pegasus. In that day the first quarter of Moon was glittering in Taurus, but I can detect the dust tail with length of 10 arc minutes and greenish ion coma. And the coma has a visual brightness of about 7th magnitude.
