Explanation: You no longer have to wake-up early to see Comet Hale-Bopp. From many northern locations, you can now go outside just after sunset and see Comet Hale-Bopp above the north-western horizon. Both writer/editors of APOD are impressed by how bright Comet Hale-Bopp has become, and how easily visible it is. The central coma is now visible from almost any location - even from a bright city. The blue ion tale is visible from a dark location. Comet Hale-Bopp's coma now rivals even last year's Comet Hyakutake, and the tail appears to be increasing in length daily.
