Question

suppose you observe the night sky in motion overhead over the course of an hour, while facing southeast in the northern hemisphere at some mid - latitude. as constellations rise in the southeast, which statements best describe their motion? (please note: not all labels will be used.) constellations undergo: positive changes in azimuth, positive changes in declination, negative changes in right ascension, positive changes in altitude, positive changes in right ascension, negative changes in declination, negative changes in azimuth, negative changes in altitude

Explanation:

As constellations rise in the southeast in the northern - hemisphere mid - latitude while facing southeast, their altitude above the horizon increases (positive change in altitude). Also, azimuth is the angular distance along the horizon measured eastward from the north point. As the constellations rise in the southeast, there is a positive change in azimuth. Right ascension is similar to longitude on Earth for celestial objects. As constellations rise, there is a negative change in right ascension. Declination is similar to latitude for celestial objects and does not have a consistent positive or negative change just based on rising in the southeast.

Answer:

Positive changes in azimuth, Negative changes in right ascension, Positive changes in altitude
