The open star cluster NGC 6530 (mag 4.6), close to the lagoon nebula (M8) in Sagittarius will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.
At a declination of -24°21', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 45°N.
From Ashburn, it will be visible between 22:52 and 03:26. It will become accessible around 22:52, when it rises to an altitude of 19° above your south-eastern horizon. It will reach its highest point in the sky at 01:11, 26° above your southern horizon. It will become inaccessible around 03:26 when it sinks below 19° above your south-western horizon.
At magnitude 4.6, NGC6530 is too faint to be seen with the naked eye from any but the very darkest sites, but is visible through a pair of binoculars or small telescope.
The position of NGC6530 is as follows:

The circumstances of this event were computed using the DE430 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.
