The Triangulum galaxy (M33) will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +30°39', it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 39°S.

From Ashburn, it will be visible all night. It will become visible at around 19:32 (EST) as the dusk sky fades, 23° above your eastern horizon. It will be lost to dawn twilight at around 06:12, 29° above your western horizon.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

At magnitude 5.7, M33 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 M33 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M33 01h33m50s +30°39' Triangulum 5.7 71'00"

The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE405 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.
