The open star cluster NGC 6530, close to the lagoon nebula (M8) in Sagittarius will be well placed for observation. 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 22:48 and 03:22. It will become accessible at around 22:48, when it rises 18° above your south-eastern horizon, and then reach its highest point in the sky at 01:07, 26° above your southern horizon. It will become inaccessible at around 03:22 when it sinks to 19° above your south-western horizon.
