Where is M47 right now?
M47 is located in the constellation Puppis, at right ascension 07h 36m 35s" and declination -14° 28' 57s. Although it is currently above the horizon at an altitude of 35 degrees, M47 is not visible because it is daytime.M47 - Open Cluster
M47 is an open cluster located in the constellation Puppis. It was discovered by Giovanni Batista Hodierna before 1654 and independently by Charles Messier in 1771. The cluster contains a rich population of young, hot stars.
M47 spans about 12 light-years across and contains around 50 stars. The cluster is approximately 1,600 light-years away from Earth and has an apparent magnitude of 4.4, making it visible to the naked eye under dark skies and easily seen with binoculars or a small telescope.
