View Full Version here: : Did anyone Sirius with Naked Eye in daylight ?

Googling around I found this page of somebody who saw Sirius in daylight with the NE in Zimbabwe. There Sirius passes overhead as it is on the latitude 17šS same as Cairns.
I did manage it one in March 1986 from Canberra in late afternoon. Looked up Sirius with an 80mm scope (which I still have but with renewed optics) and looking along the tube and I saw a very pale dot on the limit of visibility .... Yes !!!
Later attempts (from South Africa in Mar 1997 and '98) failed. Here in NL Sirius is too low in the sky.
Did somebody succeed to see Sirius with NE in daylight ?
Note: daylight == sun above horizon even when a few degrees.
NE: normal eyeglasses / contact lenses are considered as Naked Eye as long no light collecting optical device such as a telescope is used.

I have not looked however I must now :P.
I have seen Venus when it was close to the moon and always figured Jupiter and bright stars could also be seen. I look forward to a supernova as they are meant to be easily visible in the day time, perhaps it might get more people into the science.

I saw Venus in the sky about 15mins before sunset here in Auckland some years ago. I had been watching Venus every night for a while so I knew pretty much exactly where to look, even though the Sun was still up.

Surely anyone with a go to scope would be able to check this out?
It's just a matter of looking in the right place, isn't it?
I have seen both Venus and Sirius in full daylight naked eye.
It is difficult to find them, but once you have found them and get an idea where they are you can look away briefly and go back and find them relatively quickly.
It is pretty common for Radio Controlled plane fliers to spot Venus/Sirius in full daylight as they are watching their plane fly past the star ;)

I've seen Venus in full daylight years on a blue blue sky day mid afternoon when the vapour trail of a jet went right past it, then it was so obvious that it was impossible to miss it. Couldn't find it for the life of me half an hour later though... never seen Sirius in daylight suppose its not on any flight paths!
I have seen Venus many times in full daylight but sadly not Sirius.

I to have seen Venus in full sunlight the hard part is training your eye to focus at infinity when there is nothing to reference as that will generally cause you to focus well short of the target and consequently you will not see it.

Interesting; I have seen Venus, Jupiter and comet Mc Naught in daylight.

I have been keeping record on when I have viewed planets with naked eye in daylight. Venus have I logged as often as on 103 occasions, Jupiter 21 times and Mars one time (October 15, 2003). Sirius have I glimpsed naked eye after sunrise twice and comet C/2006P1 (McNaught) once in the afternoon (January 13, 2007). During total solar eclipses have I seen Mercury, Saturn, Canopus and Procyon as well.
