The open star cluster NGC 1981 in Orion's sword will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -04°25', it is visible across much of the world; it can be seen at latitudes between 65°N and 74°S.

From Seattle, it will be visible between 20:19 and 03:54. It will become accessible at around 20:19, when it rises 17° above your south-eastern horizon, and then reach its highest point in the sky at 00:08, 37° above your southern horizon. It will become inaccessible at around 03:54 when it sinks to 18° above your south-western horizon.
