Check the site in a couple of weeks for the July map.
Since the earth completes an orbit round the sun in 12 months, everything shifts westwards by 2 hours each month. Hence the map for early June at 8pm will also be correct for early July at 6pm, aside from the phenomena like moonrise/set, moon phases and the planetary phenomena which are specific to each month. Even there, from the June map you'll be able to figure out which planet is which.
If friend is carrying a smartphone and possibly binoculars I'd suggest they acquire a copy of Sky Safari, it's well worth spending some time lying on the ground looking up.
