Minor planets and related objects. XXIV - Photometric observations for /5/ Astraea

Five light curves of (5) Astraea are presented along with UBV photometric results and analyses of the pole orientation, sidereal period, sense of rotation, and color coefficients. A sidereal period of 16 hr 48 min 43.60 sec (+ or - 0.03 sec) with a retrograde sense of rotation is adopted as well as a North Pole position at +9 deg (+ or 1 deg) latitude and 148 deg (+ or - 3 deg) ecliptic longitude. It is noted that an amplitude-aspect plot indicates an amplitude of the order of 0.37 magnitude for an equatorial-aspect light curve of Astraea
