Every constellation, like the Sun, rises and sets. The best moment in which you can look for it is when it transits your meridian and it is very high in the sky. That is the moment in which you have less spanning atmosphere and less light pollution.
Only in these conditions you can see open clusters, globular clusters, bright nebulae and galaxies (Andromeda only) with the naked eye or by a small binocular (7x or 8x).

In the table are shown the dates and the hours in which the constellations are at their best, but if you suffer from insomnia you can look for much more during night because other constellations rise.
The dates shown are astronomically accurate but there is no substantial difference ten days earlier or later.

If you analyse the table you can easily understand that a constellation "stands" in the same position 15 days later and 1 hour earlier, that means that the day after you can find it in the same position 4 minutes earlier, so your observation can last months. The only limitation is sun light.

In the column "best Lat." is indicated the Latitude in which a Constellation is straight on your head (at the zenith), so, on January 5, if you like to travel you can look for a wonderful Orion near Nairobi or Singapore..., it would be worth while...


The table below shows the visibility of the constellations all over the year and it's referring to local time 0.00. Yellow boundary sectors are referring to 45°N, whatever Longitude. Boundary sectors can change more or less according to travel North or South.
