We obtained further follow-up on C/2012 S1 (ISON) on 2012, Oct. 4.6, again through the 2.0-m f/10.0 Ritchey-Chretien + CCD + Bessel R filter of Faulkes Telescope North (F65) Haleakala.

Stacking of 9 exposures, 120 seconds each, produced an image where a well developed and elongated coma measuring nearly 6"x9" is now visible, extended toward PA 280 deg.

From this stacking, the Afrho parameter was determined to be about 1530 +/- 150 cm (see panel below). The total magnitude has been measured as R= 17.7.
