COMETS C/1983 N2 AND C/1984 Q1 (SOLWIND)
     Further to IAUC 8566, R. Kracht reports two additional Kreutz
comets found and measured by himself on SOLWIND images.  Following
are the observations of C/1983 N2, which appeared generally
starlike and of mag 2-3, with a possible faint tail in the final
images; B. G. Marsden provides the following parabolic orbital
elements for C/1983 N2:  T = 1983 July 7.89 TT, Peri. = 81.43, Node
= 359.55, i = 142.23 (equinox 2000.0), q = 0.0049 AU.

     Following are positions for C/1984 Q1, which had a faint tail
and faded rapidly from mag about 3 in the first few images.
Marsden provides the following parabolic orbital elements for
C/1984 Q1:  T = 1984 Aug. 23.22 TT, Peri. = 81.04, Node = 355.72,
i = 144.14 (equinox 2000.0), q = 0.0049 AU.
