Well it's currently still raining here, so it doesn't look promising for tomorrow morning. I may have to wait until Friday morning, but if so, so be it. In case it does clear up, here is the ephemeris for ISON from my observing site on the 19th. I'll be talking about this some more during the webcast to show that ISON's orbit has not changed as is being claimed on youtube and elsewhere lately.

ISON's orbit and the resulting ephemeris were calculated using the astrometric data excluding any observations from the month of September. So if the orbit has recently "changed" as claimed, these coordinates shouldn't work.
