Observers in the northern hemisphere face a challenge this morning as the waning crescent Moon passes by M45, the Pleiades open star cluster. Unfortunately, the pair will be close to the horizon and difficult to see in the early pre-dawn twilight. Those in Australia will have better luck but the distance between the two will be greater.
