Just 5 2/3 degrees east of Zenith will be the star Nekkar. The labeled 'Beta' star in the constellation of Bootes.
Nekkar should be at RA=15h02m15s Dec=40掳21'57"N
Most star charts have grid marks labeled in RA with hours (h), minutes (m), and seconds (s).
While Declination (dec) is labeled as parts of a circle ... degrees (掳), minutes of degrees ('), and seconds of degrees (").
