Number 9: Solar Transit of Mercury



Sunrise today was at 0533hrs Local Time. I ventured out of the house to a location where I would have a clearer view of the horizon than from my yard. There are some small mountains along the eastern horizon so I had to wait until the sun rose above them to begin observing.
