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: "Ikeya-Zhang,
taken with a 4" guide refractor mounted on the big observatory
scope in Conway, AR. The comet was magnitude 3.6 with an 8 degree
tail pointing nearly due north; both were clearly visible to the
naked eye on this very dark and clear morning. You can really
appreciate the very rich star field of the winter Milky Way seen
in this 3-degree field view in Cassiopeia." |

Jorgen Blom: "Early in the
morning of April 10 I took these pictures of Ikeya-Zhang from
a fairly dark site in the archipelago east of Stockholm.A 10 minute
exposure with a 135 millimeter lens showed the comet's ion tail
stretching through the countless stars of the Milky Way to the
little, fuzzy blob on the lower right hand side of the picture.
It's the 6.7 Magnitude open star cluster NGC 7789 which is located
exactly 9 degrees from where the comet's coma was at the time." |

Clay Sherrod: "Here is a double-shot
of Ikeya-Zhang. The large image (about 1 degree of sky!) is taken
across the observatory roof in strong twilight with a 4" guide
refractor. The inset is through a 12" Meade taken at exactly the
same time. It shows the very central part of the comet, slightly
more than four times closer and more detailed at the head than
in the other shot!" |
