C/2002 C1 Ikeya-Zhang
The Great Northern Binocular Comet of 2002
Closest to Sun on March 18th 2002 at 0.51AU
Closest to Earth on April 29th 2002 at 0.40AU
Maximum magnitude 3 in late March 2002.

2002 Feb 6.48 UT 2002.
Above is a pre-perihelion CCD image taken a few days after discovery.
I estimated its brightness at magnitude 8.1.
My last pre-perihelic observation was on Feb 18.46 UT when it had brightened to magnitude 6.9

This comet peaked at magnitude 3 in late March 2002 and was an impressive binocular object
for Northern Hemisphere observers.

I next observed the comet on May 10.38 UT, when it had faded to magnitude 5.4

2002 June 2nd, 80mm lens and CCD.
Field of View 1.5 degrees wide. A short dust tail remains visible in this image.

My last observation was on 2002 July 30.54 UT when the comet shone at magnitude 12.0

Ikeya-Zhang has been linked to previous appearances in 1661 and 1273
and has thus been given a permanent periodic number 153P.
It will return in 362 yrs time.
