Another relatively faint galaxy, NGC 2090, is situated 50 arc minutes
further east of NGC 2061 and displays an extended spindle shape in a north-south direction.
The open cluster NGC 1818, situated only 50 arc minutes
to the east, is rather impressive and resembles a small, bright, round hazy patch with a compact middle (see sketch).
Three more galaxies, NGC 7232A, IC 5181 and IC 5171, are situated a further 25 arc minutes
to the west.
NGC 3256C is the closest member but very faint, situated 18 arc minutes
to the north-east of the main galaxy.
Again the trio can be spotted in a 12 arc minute
NGC 2658, situated only 35 arc minutes
north of alpha Pyxidis, contains about a dozen faint stars with some unresolved dust, indicating more members.
The group is situated only 10 arc minutes
south of the galaxy IC 4679.
These events are listed in the table on the next page, which gives the cluster's magnitude, its diameter in arc minutes
, and the approximate duration in minutes for the Moon's edge to cover the entire object.
Australian astronomers have discovered a narrow filamentlike object near the galactic center that stretches more than 20 arc minutes
MacKenty had previously detected an unexplained jetlike feature about 1 1/2 arc minutes
(240,000 light-years) in extent.
1~ only a few arc minutes
from it among the stellar riches.
Only 45 minutes later, Diego Rodriguez obtained a CCD image confirming the new star some 3 arc minutes
south-southwest of the galaxy's nucleus, and word of the discovery began spreading around the world.
The number of seconds divided by two equals the field diameter in arc minutes
At the f/8 focus of the 20-inch telescope, our camera images only 2 arc minutes
of sky, or about 1 percent of the area of M37
Nathalie Brouillet, Alain Baudry (University of Bordeaux, France), and Christian Henkel (Max Planck Institute for Radio Astronomy) discovered a giant cloud of molecular hydrogen some 14 arc minutes
east of M81, the well-known spiral galaxy in Ursa Major.
