COMET P/2009 Q2 (LINEAR-NEAT)
J. V. Scotti, Lunar and Planetary Laboratory, reports his
recovery of comet P/2003 XD_10 (cf. IAUC 8257) showing stellar
appearance on Spacewatch images obtained with the 1.8-m f/2.7
reflector at Kitt Peak (first observation tabulated below).
2009 UT R.A. (2000) Decl. Mag. Observer
Aug. 27.39043 1 18 00.41 - 7 20 05.0 21.5 Scotti
The indicated correction to the prediction on MPC 59598 is
Delta(T) = -0.10 day. Additional astrometry by Scotti for Aug. 27,
28, and 29 -- together with orbital elements for epoch 2003 (and
those below), residuals, and an ephemeris -- appear on MPEC
2009-Q68.
Epoch = 2010 Feb. 13.0 TT
T = 2010 Jan. 31.8363 TT Peri. = 16.0938
e = 0.416377 Node = 40.5285 2000.0
q = 1.989593 AU Incl. = 13.4361
a = 3.409038 AU n = 0.1565872 P = 6.29 years
COMET C/2009 Q3 (LINEAR)
J. V. Scotti, Lunar and Planetary Laboratory, reports his
recovery of comet P/2002 T1 (cf. IAUC 7983) showing a "soft"
appearance (no obvious coma or tail) on Spacewatch images obtained
with the 1.8-m f/2.7 reflector at Kitt Peak (first observation
tabulated below).
2009 UT R.A. (2000) Decl. Mag. Observer
Aug. 28.49035 4 31 39.80 +25 09 34.5 21.1 Scotti
The indicated correction to the prediction on MPC 56804 is
Delta(T) = +0.04 day. Additional astrometry by Scotti for Aug. 28
and 29 -- together with orbital elements for epoch 2002 (and those
below), residuals, and an ephemeris -- appear on MPEC 2009-Q69.
Epoch = 2009 Sept. 6.0 TT
T = 2009 Aug. 25.5302 TT Peri. = 3.8270
e = 0.639260 Node = 14.2249 2000.0
