The globular cluster M15 (NGC 7078) in Pegasus will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +12°10', it is easiest to see from the northern hemisphere; it can be seen at latitudes between 82°N and 57°S.

From Ashburn (click to change), it will be visible all night. It will become visible at around 21:16 (EST) as the dusk sky fades, 31° above your eastern horizon. It will be lost to dawn twilight at around 05:12, 30° above your western horizon.

At magnitude 6.4, M15 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

The position of M15 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M15 21h30m00s +12°10' Pegasus 6.4 12'18"

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.
