If you can manage to stay awake until about 1am and have a clear North horizon, then you might just manage to glimpse the rapidly moving Comet McNaught c/2009 R1. It is brightening nicely, currently at Mag 6.3 but expected to brighten to Mag 3.0 by the end of the month.
There is a nicely developing tail visible in long exposure images.
Check out this great time lapse video of the comet "passing by" a galaxy:
Of course you'll be battling the twilight so I suspect it'll be quite a challenge.
Clear skies are predicted for most of next week, so have a go and report your observations at the next CAS meeting (June 29th) or bring along your photos.
