A celestial alignment will occur in the early hours of July 11, when the waning crescent moon glides past the Pleiades star cluster, commonly referred to as the Seven Sisters or M45. Observers in London can best view this pairing around 3am BST by looking toward the east-north-east, though a clear horizon will be necessary given the brightening conditions at that hour.
The moon will present itself as a thin crescent with approximately 15% of its visible hemisphere illuminated, making it the most easily identifiable object in the pairing. Its sunlit edge will be oriented downward toward the horizon, while the Pleiades will appear as a compact grouping near the moon’s dark limb. To the naked eye, the star cluster typically resembles a miniature version of the Plough asterism, though most observers can distinguish only six individual stars without optical aid.
Binoculars will substantially enhance the viewing experience, revealing significantly more stars within the cluster than are visible to the unaided eye. Additionally, Mars will be positioned in the vicinity within Taurus, though it will sit even lower on the horizon, presenting a more challenging observation target amid the increasing daytime brightness.
The alignment will be observable from the southern hemisphere as well, though the configuration will differ slightly, with Taurus rising in the north-east rather than the east-north-east as seen from northern latitudes.
