The comet tail is fan-shaped, with an aperture of about 90°. This is due to the small angle of the tail respect our line of sight (about 17°). The tail is best visible with a blue filter. The tail components are at position angles between 165° and 270°, extending from the optocenter at least 1°. The dust coma is 11' diameter and the gas coma is about 42'.
