Sit back and think about this and you’ll be able to figure out your own question. You’re heading west. What appears to go that direction during the day? (Hint? It’s big and yellow.) If you are flying toward it and you leave at 11 a.m. and arrive at 1 p.m. do you think this yellow thing will leave the sky prior to you landing?
Now you’re flying away from that yellow thing because you are going east. You arrive in the morning. You leave in the evening. What comes between evening and morning? (Hint: you can often see little dots of lights during this time.)
