Mars and NGC6530 will make a close approach, passing within 0°35' of each other.

From Cambridge, the pair will be difficult to observe as they will appear no higher than 17° above the horizon. They will become visible around 18:24 (EDT) as the dusk sky fades, 17° above your south-western horizon. They will then sink towards the horizon, setting 3 hours and 7 minutes after the Sun at 20:50.

Mars will be at mag 0.9, and NGC6530 at mag 4.6, both in the constellation Sagittarius.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.

A graph of the angular separation between Mars and NGC6530 around the time of closest approach is available here.

The positions of the two objects at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Mars 18h04m30s -24°56' Sagittarius 0.9 5"6
NGC6530 18h04m30s -24°21' Sagittarius 4.6 15'00"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 56° from the Sun, which is in Virgo at this time of year.
