Noctilucent cloud season which are a high altitude phenomenon at around 82km up in the mesosphere these clouds are ice sheets of tiny ice crystals made from
meteor dust that hang in the atmosphere.
They have been spotted already and are best seen just before the Sun rises or after it sets as it lights up these from beneath giving you a whispy blue, white cloud that’s not that common. So if your out about 45mins to an hour after or before sunset or sunrise keep an eye out.
Early morning on the 5th there are two shadow transits today, as Jupiter rises around 1.30am IO and Ganeymedes shadows will be on the planet. IO’s shadow will be moving quicker and will move away from Ganeymedes moving off the planet at around 3.17am.
A bit of asteroid hunting for those keen astronomers, Asteroid 3 Juno reaches opposition in the serpent bearer you will need a moderately sized scope to pick out the white dot in relation to the back ground of stars. It is slap bang in the middle of the constellation so a bit of star hopping may be needed.
Back to Jupiter in the early hours and between 2.36 and 2.41 the Moon Europa will be eclipsed partially by the shadow of IO. So a moons shadow will partially go across another moon making it get slightly dimmer.
The Moon is out of the way so a great time to have a look at our telescope and binocular objects of the month.
Grab your binoculars and have a look at Polaris the north star you should see a ring of stars with Polaris being the brightest, known as the diamond ring asterism it looks like a ring with Polaris being the diamond shining bright, great for those wanting to propose although it may cost you to put that ring on their finger.
Those with telescopes see if you can spot the great Hercules globular cluster on the square of the constellation, between the top two stars is a magnificent glob of thousands of stars some of the oldest in our galaxy.
Today is the partial solar eclipse. At around 10am it will slowly cross the top of the Sun creeping across until 12.35pm where
it leaves it, have a lunch time picnic or pop out for a walk and see if you notice the light dimming slightly around you at its peak at 11.19am , which is a
weird sensation and the last one I noticed that the birds actually went quiet to.
Pop back to Jupiter again as it rises at 1.15am and you’ll see the Moon Callisto moving across the planet leaving at 3.30am.
Just after sunset see if you can spot the really thin 1% lit crescent Moon that’ll be below the planet venus shining bright.
This afternoon you’ll see the Moon has moved even closer to the goddess of beauty Venus and may be slightly easier to spot for you.
Tonight its Mars turn to be visited by the Moon, the God of war is still in the sky shining blood red but will soon be gone as we move away in orbit.
Today is the northern hemispheres summer solstice marking the longest day of the year, Traditionally, the summer solstice period fell between the planting and harvesting of crops, leaving people who worked the land time to relax. This is why June became the traditional month for weddings.
Bootid meteor shower starts building up to its peak on 27th, look towards the constellation Bootes. Find the bright star called Arcturus that is part of this constellation, the meteors will radiate from slightly further above this star with around 10per hour although it is an unpredictable shower with some recording over 100ph in the past.
Another double shadow transit on Jupiter if you missed the earlier ones, IO and Callistos shadows will start from 4.40am with IO/s joining it just after 6am so the rising Sun may get in the way but you should be able to spot them.
Venus and Mars close in on each other look towards the West-Northwest around 11pm and spot the two planets see if you can tell which is which from their colours.
Don't forget this month's naked eye object is – the Noctilucent Clouds, the binocular object is – Polaris Diamond Ring Asterism and the telescope object – Hercules Globularcluster.
Clear skies guys, and remember... there’s a billion worlds in your back garden!
