The Jeddah Astronomical Society explained that the moon will appear from the southeast horizon at sunset and its apparent size will be large when it is close to the horizon and its color is red-orange, and its trajectory in the night sky will resemble the trajectory of the January sun across the daytime sky, so the moon will not be observed in the northernmost regions of the ball. Earth at all, because the July full moon, like the January sun, is too south over the dome of the sky to be seen from northern latitudes.
