Today:
Tonight near midnight, the bluish-white star Vega is nearly overhead, while the brilliant pale-orange Arcturus is about half way up from the horizon in the west. Between them, about two thirds of the way from Arcturus up to Vega, a bow-tie shaped pattern of stars can be found, outlining the figure of Hercules.
Monday:
The star Capella is right on the northern horizon, due north at 11:45 PM EDT. While essentially not viewable right now, because it so low in the sky, it never sets at our latitude. By midnight, it will be rising in the north-northeast. In six months from now, it will be almost exactly overhead during the bitter cold evenings of January.
Tuesday:
The second brightest star in the summer sky, Vega, appears nearly overhead at midnight. From the zenith, lower your focus into the east, still quite high, where another bright star catches your attention, Deneb, highlighting the tail feathers of the constellation Cygnus, The Swan.
