Question:
You and a few of your closest friends recently heard that Betelgeuse, a red supergiant star in the Orion constellation, could go supernova any day now. To ensure that you all don't miss the spectacular light show it will inevitably create when it goes supernova, you promise your friends that you will keep an eye on it and let them know when it happens. On December 27, 2039 at 7:07 pm, Betelgeuse finally explodes in a supernova. Luckily, at the moment it explodes, it is above your horizon.
In the following parts, describe the coordinates (use the terms Right Ascension, Declination, Altitude, and Azimuth) that you would give to each friend. (DO NOT GIVE ME NUMBERS OF ANGLES!) Also, imagine that you have called them all at 7:10 pm (the same exact time).
Each part is worth 2 points. Write your answers in the space below. Please label them with the correct letter!
a) You call a friend in Stillwater, who answers immediately and goes straight outside to see the supernova. What are the best coordinates of Betelgeuse to give this friend? Explain your reasoning.
b) You call a friend in Stillwater, who does not answer because they work until 10 pm. Knowing that they probably won't get your message until 10:05 pm, what are the best coordinates of Betelgeuse to give this friend? Explain your reasoning.
c) You call a friend in Thailand, who answers immediately and goes straight outside to see the supernova. What are the best coordinates of Betelgeuse to give this friend? Explain your reasoning.
d) You call a friend at the South Pole, who is doing research at the Amundsen–Scott South Pole Station, and they answer immediately. They go straight outside to see the supernova. What are the best coordinates of Betelgeuse to give this friend? Explain your reasoning.
e) Which one of your friends is going to be mad at you for telling them about a supernova that they will not be able to see? Explain your reasoning. If None, answer "None".
