To further help you in finding Comet ISON before it gets too close to the sun to see, I’ve prepared four maps, one for each morning Nov. 22-25. Previous maps I’ve made show the comet’s position about one hour before sunrise for mid-northern latitudes, but because ISON is may now bright enough to be seen in mid-twilight, I’ve advanced the time to just 55 minutes before sunrise.
Arcturus, Spica, the planets Mercury and Saturn and of course the horizon itself will be your guides to finding ISON. One of the main reasons for making separate daily maps has to do with the ever-changing positions of the Mercury and Saturn near the horizon. Add in ISON and you’ve got three bodies shifting around at the same time. Trying to show all three at once over a span of time can get confusing. Individual maps recognize the unique celestial arrangement for that particular day.
If you are going out to find the comet, you’ll need clear skies and a view as close to the southeastern horizon as possible. Start looking with binoculars a full hour and a quarter before sunrise, so you can anticipate its rising. Have at it and good luck!
