May 28 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 18:40 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
** No doubt that most of our first Semester is on hold of the Planets in retrogradation.
