COMET COMMENTS FOR AUGUST 1997
By Don Machholz
A new comet has been recently discovered in the southern sky.
Meanwhile, Comet Hale-Bopp continues to dim in the southern sky.
Both comets will be briefly visible to many Northern Hemisphere
observers in a few months.
The new comet was discovered by Vello Tabur of Australia on July 2.
He used an 8-inch f/4.7 reflector to find the tenth magnitude object,
which was situated in the morning sky, far south of the sun and out
of view of Northern Hemisphere observers. It was Tabur who had made
the last visual discovery-nearly a year ago. Comet Tabur (C/1997 N1)
will appear in the evening sky for northern observers in early
September.
The solar-orbiting satellite SOHO has picked up five additional small
comets as they headed toward the sun. Most of the 17 comets found by
the satellite belong to the Kreutz Sungrazing Group, all were faint
and seen only by the satellite. Most disappeared as they rounded the
sun.
COMET HUNTING NOTES: With Tabur's find, six of the last seven
visually-discovered comets have been found south of the celestial
equator; and 14 of the last 17 visually-discovered comets have been
found in the morning sky.
