It's visible now, already a couple of magnitudes brighter than the ephemeris prediction, so it seems it will be quite a bright object at eclipse time!

I've attached a chart generated in Starry Night showing the comet position. Location is mine, SE of Tahiti, but won't be much different where you are. Comet 141P Machholz is also marked but it will be very dim, predicted at mag 14 or so.

Edit: The scale of the Sun is slightly enlarged in the pic - just the way SN shows it at default scale. As you zoom in, correct scale is reached. Check it in your own planetarium programs.

Hey, thanks Rob!

I wont have a chance of trying to image the comet, but should have plenty of time to look for it visually (binos). Mercury will act as a convenient signpost.

Cheers
