Here are January's currently known bright comets.  Predictions are
every fourth day for first even hour after comet-rise.  Motion 
is generally slow, so these are sufficient to chart its movement 
in an atlas to find the objects with binoculars or telescopically. 
  Brightnesses are only rough estimates and the actual brightness 
may vary considerably. 
   Bonne Chance, 
   Don Barry
  
N.B.  Predictions are for Atlanta, but RA and DEC are valid everywhere,
      and AZ/EL are approximately valid if you use your local time and
      are in the U.S.
