The Pinwheel Galaxy M101
(NGC 5457; mag 7.9) in Ursa Major
will be well placed in the evening sky in coming weeks.
On 22 April it
will reach its highest point in the sky at around midnight
local time, and on subsequent evenings it will culminate four minutes earlier each day.
From Los Angeles , it is visible all night. It will become visible at around 20:32 (PDT), 41° above your north-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:52, 69° above your northern horizon. It will be lost to dawn twilight at around 05:07, 41° above your north-western horizon.
At a declination of 54°20’N, it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 15°S.
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 |
| M101 | 14h03m10s | 54°20’N | Ursa Major | 7.9 | 0’00” |
The coordinates above are given in J2000.0.
