Comet Hale-Bopp has faded in the past few weeks. For Hale-Bopp [

], promised as the Great Comet of 1997, this was a bit of a disappointment -- but not entirely unexpected. Comet Hale-Bopp [
http://antwrp.gsfc.
] continues to approach the Sun [
http://antwrp.gsfc.
] - making the comet itself brighten, but now the Earth [
http://antwrp.gsfc.
] is moving away from it - making the comet appear to dim. Experts disagree on just how bright Hale-Bopp [
http://encke.jpl.na
] will become. Optimists hope it will eventually outshine Comet Hyakutake [
http://antwrp.gsfc.
], but some pessimists now expect no better than 3rd magnitude - hardly visible from well-lit cities [
http://antwrp.gsfc.
]. Comet Hale-Bopp [
http://www.eso.org/
] still appears to be, however, a very large comet, and is sure to show much activity as it nears the Sun. The comet should reach peak brightness in March 1997. [
