Ephemeris of C/2012 S1 ISON January 10, 2014UTC Inverted Version
I tried imaging of the ephemeris, and there existed a slender sausage-shaped object near the ephemeris of C/2012 S1 ISON.
I could not find such object on The Second Palomar Observatory Sky Survey (POSS-II) IR images.

This movie may help the comparison easier.
equipment: Leica Apo-Elmarit-R 180mm F2.8 and Canon EOS 5Dmk2-sp2, modified by Seo-san on Takahashi EM-200 temma 2 Jr. equatorial mount without autoguiding
exposure: 7 times 1,200 seconds at ISO 1,600 and f/4.0
The first exposure started at 17:38:21 and the last at 19:40:42 January 10, 2014UTC.
site: 1,530m above sea level at lat. 35 48 48 N. and long. 138 39 16 E. in Makioka, Yamanashi
Ambient temperature was around -13 degrees Celsius, 9 degrees Fahrenheit.
(update on January 14, 2014JST) I found the same slender sausage-shape on my old frame of C/2011 L4 PANSTARRS, taken on May 21, 2013, and it is not the remnant of C/2012 S1 ISON.
