July sees a marked change in the evening sky. The spring groups, Leo and Virgo, have faded into the twilight; Antares is very low in the south-west after dark. The Great Bear is in the north-west, with the W of Cassiopeia gaining altitude in the north-east. The brilliant blue Vega is almost overhead, which means that Capella, on the opposite side of the pole, is so low that it will probably not be seen, though from Britain it never actually sets. The ‘Summer Triangle’ of Vega, Deneb and Altair is now dominant; the star-clouds of Sagittarius can be seen over the southern horizon, but much of the southern aspect is filled with the large but relatively dim constellations of Hercules, Ophiuchus and Serpens. The Square of Pegasus is starting to come into view in the east; Arcturus shines in the west.
