Solar Rotation number 2205 starts on the 12th
conjunction on the 6th
when it passes less than 1° north of the Sun. It will
therefore not be visible during the first half of the month being
so close to the Sun. It may be possible to locate the planet in
the bright twilight sky, low down in the west using a pair of
binoculars during the second half of the month. On the evening of
Mercury will be in a line that joins the two bright stars of
Gemini, namely Castor and Pollux.
Will be easily visible in the
western sky after sunset, shining at magnitude
-3.9 to -4.1. A crescent Moon (14% illuminated) will be 6° to
the left of Venus on the evening of the 16th
and should be a nice view through binoculars. See the open star
cluster Messier 44 upper right of the Moon on the same night. You
will need to use binoculars to see the cluster due to the bright
in the constellation Capricornus throughout the month, shining at
-1.2 to -2.2.
The disc of the planet as seen through a
telescope will increase in apparent diameter from 15.3 to 21.0 arc
seconds. The planet is low down in Manx skies and the image as
seen through a telescope will be somewhat degraded due to poor
seeing conditions. You may however glimpse some of the dusky
shadings on the planet.
Rises at 17.58h (in daylight)
on the 1st,
shining at magnitude
-2.5 in the constellation Libra. By the end of the month, the
planet will rise mid afternoon and will be past the meridian by
the time darkness falls.
The Great Red Spot may be seen
using a telescope in good seeing conditions. Using a light blue
filter with an eyepiece will help. Opportunities to see the Great
Red Spot from Mann occur on a regular basis.

the moons orbit Jupiter, there are occasions when the shadow of
the moons can be seen upon the surface of Jupiter and the moons
can transit across Jupiter's disc. Also, the moons can be seen to
be occulted or eclipsed by Jupiter. There are many events
throughout the month. See periodicals such as the BAA
Handbook, Astronomy Now
and Sky at Night
magazines for listings.

On the 28th,
the very near Full Moon is 2.8° upper right of Saturn.
The brightest moon of Saturn,
Titan will be east of the planet on 13th ,14th

meteors are active from May to July with two peaks of activity on
month. The shower is weak with only 5 meteors per hour at best
Radiant for the peak on the 10th
at RA 17h56m Dec. -23° and the radiant for the 20th
at RA 17h20m Dec. -20°.

events about 20 minutes before the above times to allow for
differences in your latitude and longitude. This will give you
time to locate the star that is about to be occulted.

is a month where noctilucent clouds may be seen in the northern
skies. They appear as glowing electric blue clouds in the middle
of the night and some displays can be vary bright. These clouds
are at very high altitudes, around 80 km high and it is this high
altitude that makes them glow with sunlight illuminating them from
below the northern horizon. On the Spaceweather.com
web site, there is a graphic showing showing latest observations
