cmpbsdb@gitpyr.UUCP (Don Barry) (11/29/85)
The following is a list of current bright comets (visible in modest
instruments or with the naked eye) for the month of December. Each
comet's position is provided every 4th day if visible, with elements
given on the hour after local rise. Although the ephemeris is for
Atlanta, the RA and DEC of the object are valid anywhere in the world,
and the azimuth and elevation are approximately correct in the USA if
local time is used. LHA gives local hour angle, and RANGE is
distance in a.u. to the object from the earth. Note that Comet Thiele
has not been mentioned in the december periodicals, even though it was
discovered more than a month ago. (Such is the state of fast-changing
information in the media - praise goes to Brian Marsden at the Smithsonian
for timely and accurate work). Comet Ciffreo, discovered only two weeks
ago, is not included because it is not expected to brighten beyond
magnitude 9.5.
Comments welcome. I intend to continue to provide updates on comet
positions, as there seems to be interest. Suggestions would be
appreciated.
