Bode's galaxy (M81, NGC 3031) in Ursa Major will be well placed for observation. It will reach its highest point in the sky at around midnight local time.
At a declination of +69°03', it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 0°S.
From Cambridge, it will be visible all night because it is circumpolar. It will be highest in the sky at 23:42, 63° above your northern horizon. At dusk, it will become visible around 18:27 (EDT), 42° above your north-eastern horizon. It will be lost to dawn twilight around 05:29, 40° above your north-western horizon.
At magnitude 6.9, M81 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.
The position of M81 is as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
