Clear
Observed with the naked eye.
Again observed the relationship between the positions of Jupiter, Antares, and Luna. The moon has shifted dramatically in 24 hours, and now lies directly beneath Antares and Jupiter so that a straight line perpendicular to the horizon has been formed. This demonstrates parallax and how the relationship between the stars doesn't change because they are so far away, but the relationship between the moon and the stars does because the moon is much much closer to us.
