     E. Schwab, Egelsbach, Germany reports the recovery of comet P/2005 R1
(cf. IAUC 8595) on CCD images taken by D. Abreu with a 1.0-m f/4.4 reflector
at the European Space Agency's Optical Ground Station at Tenerife.  The comet
shows a faint tail extending about 10" in p.a. 250 degrees on the June 13
images.

The indicated correction to the prediction by S. Nakano in the ICQ's 2018
Comet Handbook is Delta(T) = -0.07 day.  The following linked orbital
elements by G. V. Williams are from 360 observations spanning 2005 July 5 to
2018 June 14 (mean residual 0".6):
