| C/1999 U1 (Ferris) New comet C/1999 U1 by W. D. Ferris (Lowell Observatory) was found on October 18, 1999, and its follow-up observations showed that the comet already passed its perihelion in August 1998. Estimations of past comet's brightness yield a value of 13-14 mag. for the entire 1998! The only reasonable explanation why it was not discovered earlier is that the comet located in the Southern hemisphere, but most of the professional dedicated program search new objects on the Northern sky. This proves that there is still a good opportunity for any amateur of astronomy to find a new object on the sky, and RedShift does help you! (Ref: MPEC 1999-U19.) creation date: 31:10:1999 |
| C/1999 T2 (LINEAR) A new comet was discovered in the course of LINEAR project on October 4, 1999. According to the first determinations of its orbit, comet C/1999 T2 will pass the Sun in November 2000 at 3 AU (ref: MPEC 1999-T64). creation date: 31:10:1999 |
