COMET P/2008 Q4 (LONEOS)
M. Jaeger, Stixendorf, Austria, reports his recovery of comet P/2001 R1
(LONEOS) on four CCD images obtained with a 0.20-m f/2.8 reflector. There was
a small coma (< 20") and a tail extending 3' in p.a. 275 deg. One of the
images was measured by W. Vollmann, with the following result:
2008 UT R.A. (2000) Decl. Mag.
Aug. 31.08719 07 39 31.16 +25 12 23.9 16.5
Confirmatory measurements were made by G. Sostero, E. Guido and P. Camilleri
on CCD frames obtained with a 0.30-m f/6.6 reflector at Skylive Observatory,
Catania, Italy, on Sept. 1.1, the magnitude being given as from 16.5 to 16.9.
The indicated correction to the prediction on MPC 54169 is Delta T = -0.42 day.
On learning of Jaeger's recovery, M. Meyer, Limburg, Germany, detected
and measured prediscovery positions on Palomar NEAT frames obtained on 2001
Aug. 9 and 14.
The various measurements, improved orbital elements, residuals and an
ephemeris are given on MPEC 2008-R09.
