Summer Solstice occurs on Friday, 21st June 2013 at 06:04 BST (05:04 UTC) when the Sun’s apparent Northerly motion in the sky reaches a standstill in Gemini. This is the longest day of the year, and marks the start of Summer in the Northern Hemisphere. After this point, the days start getting shorter and the Sun begins to sink back to the South until the Winter Solstice in December.

The Moon reaches Perigee – the closest point in its orbit to us – on 24th June. This particular Perigee is the closest of 2013, with the Moon’s distance being 355,439km – this is less than 21 times the distance from Liverpool, UK to Sydney, NSW, Australia.

Mercury starts the month relatively high in the sky – in fact, higher than Venus – peaking on about June 7th. Its position in the sky is much the same as last month, so the charts given in May 2013’s “What’s Visible?” can be used as a guide along with the more precise table above this paragraph.
Venus spends most of the month lower in the sky than Mercury, not overtaking it until 21st June when the two planets have a conjunction. Unfortunately they will be quite low in the sky (see table above) and close to the Sun, and this event will be difficult to observe.
Mars is still lost in the morning twilight during June 2013, and observing it will be quite difficult
Jupiter reaches Solar Conjunction on 19th June and so cannot be observed this month.
Saturn passed Opposition on April 28th, however it is still very well placed for observing. Look for it quite high in the South at about 22:00 BST.
Neptune is slowly becoming a viable object for observing again, rising at about 01:02 BST by the 15th June 2013. The planet reaches Opposition in August 2013.
Near Earth Asteroid 1998 QE2 made its closest approach to Earth on May 31st, and while not a particularly bright object for visual observation at a predicted magnitude of 10.5 to 11, it is of interest to those making radar observations, such as NASA.
Comet C/2012 S1 (ISON)
Comet ISON spends June within the orbit of Jupiter and outside the orbit of Mars, as it approaches the inner Solar System. It is still extremely faint, and is expected to be so for some time yet.
Comet C/2011 L4 (Pan-STARRS)
Comet C/2011 L4 (Pan-STARRS) begins the month about 6° from Polaris, and during June crosses Ursa Minor and passes into Draco, reducing in (predicted) brightness from about magnitude 9.5 to almost magnitude 11 as it goes.
On 19th June 2013 Comet Pan-STARRS will pass within a degree of the star Kocab (β-Ursae Minoris).
Comet C/2012 F6 (Lemmon)
Comet C/2012 F6 (Lemmon) is very faint now, although much higher in the sky now than it was during May. Between about the 11th and 12th of June, it passes within 5° of M31 (the Andromeda Galaxy).
