The pinwheel galaxy (M101, NGC 5457; mag 8.3) will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.
At a declination of +54°20', it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 15°S.
From Ashburn, it will be visible all night. It will become visible around 21:03 (EDT) as the dusk sky fades, 46° above your north-eastern horizon. It will be lost to dawn twilight around 05:16, 47° above your north-western horizon.
At magnitude 7.9, M101 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 M101 is as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0.
