COMET P/2019 E2 = P/2005 Y2 (McNAUGHT)
     E. Schwab, Egelsbach, Germany, reports the recovery of comet P/2005 Y2
(cf. IAUC 8652) on CCD images obtained on Mar. 10 UT by D. Abreu with a 1.0-m
f/4.4 reflector at the European Space Agency's Optical Ground Station,
Tenerife; the comet shows no coma and no tail on stacked images with a total
exposure time of 600 s.  Schwab also forwards confirming observations made at
his request by L. Belli and P. Breitenstein (Pascal-Gymnasium, Muenster,
Germany; submitted by L. Kurtze to Schwab) using the 2.0-m "Faulkes
Telescope North" at Haleakala, Hawaii; again, the comet shows no coma and no
tail in stacked images with a total exposure time of 540 s.  The astrometry
is tabulated below.

The indicated correction to the prediction by S. Nakano in the ICQ's 2019
Comet Handbook is Delta(T) = +0.04 day.  The following linked orbital elements
by G. V. Williams (from 146 observations spanning 2003 May 30-2019 Mar. 18)
and an ephemeris appear on MPEC 2019-F27.
