Across much of the world the Ptolemy cluster (M7, NGC 6475) in Scorpius will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -34°49', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 35°N.

From Ashburn (click to change), it will not be readily observable since it will lie so far south that it will never rise more than 16° above the horizon.

At magnitude 3.3, M7 is tricky to make out with the naked eye except from a dark site, but is visible through a pair of binoculars or small telescope.

The position of M7 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M7 17h53m50s -34°49' Scorpius 3.3 1'20"

The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
