Mercury will not be visible to the naked-eye on sunrise. It is a thin
crescent of 0.2 magnitudes at this enlongation. Over the next week, it
will remain within 2 or 3 deg of Venus and will brighten to -1.1 mag
through 8/16. This might make a nice photo op to make an animated gif
movie over the next week, for those of you with the interest to get up
before sunrise for the next week.
