2) Your friend says there is a supernova with an azimuth of 8 degrees, altitude of 74 degrees, and an apparent magnitude of 2.0 in the sky at 10:00 pm on July 28, 2017 in South Hadley. It is a perfectly clear night. Should you be able to see this object in South Hadley on July 28, 2017 at 10:00 pm using just your eyes? Why or why not? Solution Yes. Because velocity of light is absolute..
