Across much of the world the second brightest globular cluster in the sky, 47 Tuc (NGC 104), in Tucana${CLOSING_PUNCTUATION} will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -72°04', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 2°S.

From Ashburn (click to change), it will not be observable because it will lie so far south that it never rises above the horizon.

At magnitude 4.0, 47-Tuc 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 47-Tuc is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
47-Tuc 00h24m00s -72°04' Tucana 4.0 30'54"

The coordinates above are given in J2000.0.
