• A fax message from Mr. Hirohisa Sato reports that a 9th-magnitude
comet was discovered in Australia. The following is an orbit calculated
by Mr. Kenji Muraoka based on 43 observations made during April 16-18,
1999. According to him, this comet will become visible in June as a 7th
or 8th magnitude object in mid-May in Japan. However, it may be very close
to the evening sun.Comet C/1999 H1(Lee) T = 1999 July 11.42000 TT Peri.= 39.68000 Node = 161.96900 2000.0 Incl.= 149.51500 q = 0.7149500 AU m1 = 7.50+5log(delta)+10.00log(r) 1999 R.A.(2000) Decl.
