Although Comet
Ikeya-Zhang is approaching our planet, it is also fading as it recedes
from the Sun. Astronomer Clay Sherrod reports on April 18 that "Ikeya-Zhang
is just visible to the naked eye and has dimmed almost one-half magnitude
since April 12." Nevertheless, there's still time to see
the comet before it vanishes. Get up before dawn any morning this
week or next and look north near the W-shaped constellation Cassiopeia;
the comet is a fuzzy blob about as bright
as a 4th magnitude star.

Clay Sherrod: "The comet is
fading! Although visible low on the northeast horizon this morning
to the naked eye, I gave it a magnitude 3.9 with only about a
4 degree tail. Note the very nice spike coming from the coma,
or head, which was quite obvious in binoculars." |

Robert Cash: "Here
is a mosaic image I made of the Comet Ikeya-Zhang on the morning
of April 14, 2002. From my home in Fountain Hills, AZ (North-East
of Phoenix) The telescope is a Meade 10" SCT on a Meade LXD-650
computerized equatorial mount. Camera is a SBIG ST-237 CCD. Exposures
were 22-seconds." |

John Codiale gathered much data
in these impressive two images, which include spectral analysis.
Obtaining spectra helps us to determine the actual composition
of the comet. |

Chris Schur captured this beautiful
image of Ikeya-Zhang's deep green coma. He exposed his film for
15 minutes with each color filter (RGB), then stacked the exposures. |

Jimmy Westlake: "Three new
images of Comet I-Z taken the morning of April 12, 2002 from the
Flat Top Mountains near Yampa, CO, elevation 9000 ft. What the
comet is losing in brightness, it seems to be gaining in detail
as it closes in on Earth." |

Great detail is visible in this
beautiful image of Comet Ikeya-Zhang by Dominic Cantin. He used
an 8-inch schmidt-camera @ f/1.5 with Fuji 800 film. The image
consists of three stacked five-minute exposures. |
