Daylight comet...?
Jan. 15th, 2007 10:41 amDon't know how long this will stay current but you may be able to wander outside and see Comet McNaught during the day:
http://www.spaceweather.com/ (it is the 14th Jan posting but US time, so may still be bright here... translate south to north - it should be below the sun prior to your local siderial noon and above the sun after.)
Just remember to be very careful when looking in the direction of the sun... I plan to carefully try to use the veranda roof to block things...
Stil heading to the beach this evening.
Edit: better comet link here from the comet's discoverer based at SSO including southern hemisphere (well, Sydney latitude) viewing info and brightness info.

From the site:
The best geometry occurs on Jan 15, with the comet starting to move away from the sun (now 7 degrees) and almost directly above the position of the sun at sunset. The head will set about 39 mins after the sun, although the azimuth at which it sets will be 5.0 degrees to the left of the sunset point. It is quite reasonable to expect the tail to remain visible up to an hour after sunset, so it may be seen in a dark sky.
On Jan 15 the comet is already 3 degrees from Mercury, up to the left.
By Jan 16, the effect of forward scattering will have dropped back to about zero and the comet will already be heading away from the Sun and Earth; back to the obscurity of the Oort cloud. Although now clearly fading, it will be moving higher into the southern sky away from the sun. At sunset on the 16th, the comet will be about 10 degrees from the sun and just left of directly above the Sun at sunset. It will set 54 mins after the sun, 9 degrees to the left of the sunset point.
From Jan 17 onwards, the comet, although fainter, should be well visible in the darker skies. It then moves into the SW sky at roughly a 45 deg angle up to the left of the sunset point. The angular distance of the comet from sun at the time of sunset from Sydney then increases on a daily basis:
