COMET P/2015 G1 = P/2008 S1 (CATALINA-McNAUGHT)
An object found on infrared images taken with the Near-Earth Object
Wide-field Infrared Survey Explorer (or NEOWISE; formerly the WISE satellite)
(tabulated below; optical-wavelength magnitude estimated) has been
identified by G. V. Williams as recovery observations of comet P/2008 S1
(cf. IAUC 8977, 8978).

The indicated correction to the prediction by Williams on MPC 79350 is
Delta(T) = -0.11 day. The following linked orbital elements by Williams
(from 76 observations spanning 2008 May 2-2015 Apr. 8) and an ephemeris
appear on MPEC 2015-G17.
Epoch = 2015 June 27.0 TT
T = 2015 July 1.75534 TT Peri. = 203.66504
e = 0.6652763 Node = 111.36381 2000.0
q = 1.1967322 AU Incl. = 15.07377
a = 3.5752833 AU n = 0.14579357 P = 6.76 years
