'When, as a child, I laughed and wept, time crept.

When, as a youth, I dreamt and talked, time walked.

When I became a full grown man, time ran.

When, older still, I daily grew, time flew.

Soon I shall find, on travelling on, time gone.

O Christ! Wilt Thou have saved me then?


Some lines written on a clock in the Cathedral Church of Christ and The Blessed Virgin Mary, Chester, U.K. It is attached to the clock case in the north transept of the cathedral and was written by Henry Twells (1823 - 1900).



The clock of life is wound but once

And no man has the power

To tell just when the hands will stop

At late or early hour.

Now, is the only time you own,

Live, love, toil with a will.

Place no faith in "tomorrow" for

The clock may then be still.

John's SkyNotes

The JUNE NIGHT SKY, 2021. The planetary positions shown are correct for the end of the month. This chart shows the whole sky.


 This is an educational site (I was, and am a teacher!), which is updated daily. I invite you to download any of the material you find here. Please feel free to download any of the content, which could be of use, or of interest to you. That is what this 'SKYNOTES' website is here for, after all! 


Welcome to jonvran.co.uk, John's simple astronomy site where you will find information about what is happening in the night sky from the point of view of Scarborough in the United kingdom, latitude 54 deg. 17 minutes north, longitude 00 deg. 25 minutes west,(situated on the east coast, midway between London and Edinburgh, and also mainland Britain); as well as what I hope are other interesting bits and pieces, of use to everyone.

Historically, these 'Skynotes' are a direct cyber-descendent, of the paper Sky notes I prepared, for many years, by hand, for members, at each meeting of the Scarborough Astronomical Society from the moment the Society began in February, 1976. In those days, I produced all the illustrations including the star charts by hand, but now, with the advent of excellent astronomy software programs, I am able to use much better graphics, for which I must thank the many programmers who have produced these wonderful software gems. In the credits section you will find a list of these amazing sources which allow me to continue to produce my 'Skynotes', for the benefit of all. It does not seem that they have been produced continuously for over 46 years, but as the Latin inscription reminds us: tempvs fvgit ! (time flies)!. There are many 'pages' in this different version of 'Skynotes'. These are listed in the MENU at the top of the page. My hope is that you find within them something of interest, and may I, here, express my gratitude to the many people who have already visited, this, my small contribution towards the popularisation of astronomy, which has been my lifelong aim and ambition.

I record here also a special 'Thank-you' for two very special teachers. First, Miss M Walker (later Mrs Martin). I was in her form at Normanton Secondary Modern school, before transferring to Normanton Grammar School at the age of 13. She gave me a small note nook in which to write about and draw events taking place in the night sky. This was to be the tiny 'seed' which would eventually grow into these 'Skynotes'. Secondly, I owe a huge debt of gratitude to the late Senior English Master, of Normanton Grammar School, Mr. T Hewson, who made me stand up in class during 'English' on Tuesday afternoons, and read aloud, to the class, several pages of Gulliver's Travels, by Jonathan Swift, despite the difficulties I had, at that time in reading words. Thanks to him, I can now read fluently; but more importantly, he taught me to have confidence, to be able to share my love of astronomy with all to whom I have been invited to speak; and ultimately to become a teacher myself.

 It is my hope that you will enjoy these pages, and return here often to take what you will from this site, as the months change, the result of Earth's journey around the sun.

May you too, always follow safe paths, and have clear and unclouded skies, in all the many aspects of your life!


Finally, I want to say a huge 'Thank You!' to friends, collegues and some of my ex students who provide me with excellent images which they have, very kindly, given me permission to use.

 The BLOG (About Me) bit is on a separate page. You can find it, if you are interested, via the MENU above!

PLEASE NOTE : Because of the size of this FRONT PAGE, which resulted in the slow loading of the material on some machines; I have created another additional page. It is called 'FRONT PAGE continued' and can be reached using the MENU above.

You will find there, illustrations of Saturn and its fascinating moon ENCELADUS, thought to be a possible abode of life, as is Jupiter's satellite Europa (also to be seen on this additional page)

SKYNOTES are available. Use The MENU above to find the current month's SKYNOTES.

ASTEROIDAL OCCULTATIONS for THE CURRENT MONTH accessible via the Menu above (ASTEROIDAL EVENTS). Thanks For those Andrej !

JUNE 16 at 21h UT.... WAXING CRESCENT. NEW MOON was on JUNE 10 at 10h 53 UT (Eclipse). FIRST QUARTER is on JUNE 18 at 03h 54 UT



JUNE 17 : The SUN'S celestial positions, as seen from Earth, at 12h UT.
Astronomical Constellation : TAURUS.
Astrological Sign: GEMINI. On JUNE 21, at 03h 32 UT the SUN enters the astrological sign of CANCER, the Crab. This is the moment of the SOLSTICE, the beginning of SUMMER in the Northern Hemisphere, and the beginning of WINTER, south of the EQUATOR.

REMEMBER ------- NEVER LOOK DIRECTLY AT THE SUN unless you have the proper astronomical filters for the purpose, NOT the one often provided by the telescope manufacturer. IT IS SAFER TO PROJECT THE SUN'S IMAGE ONTO A SCREEN.

Never look through view finders at the sun. instead look at the shadow of the instrument on a card. When the shadow is as small as it can be, it is pointing towards the sun, and you will see the safe image of the Sun on the card. NEVER LOOK DIRECTLY AT THE SUN------ IT CAN BLIND YOU !

The PLEIADES and MARS in conjunction, FEBRUARY 28, 2021. Imaged by Wakefield Astronomer Maurice Bradwell. Notice the contrasting colours of the hot blue stars and the 'Red Planet'.
You can see also that Maurice has captured the brightest areas of
the Pleiades nebulosity, especially in the vicinity of the star Merope
Thanks Maurice



The times when ALGOL (Beta Persei), the famous eclipsing variable star reaches its MINIMUM brightness may be found in the monthly SKYNOTES summary for each month. The star has a page dedicated to itself also, accessible via the MENU above.

ASTRONOMICAL EVENTS due this month may be found in the MONTHLY SKYNOTES, accessible via the MENU above.

A PARTIAL ECLIPSE OF THE SUN - OCTOBER 25, 2022. A partial eclipse is visible from the UK !The 'layers' in the 'Eclipse Zone' on the map show the percentage of Sun covered by the Moon. Each segment is a 10% increase, starting at the edge (0%).
Future solar and lunar eclipses for UK, may be found using the MENU above.

PARTIAL ECLIPSE OF THE SUN - OCTOBER 25, 2022. This diagram shows the maximum extent of partiality as may be seen from here, occuring at 09h 55 UT(10h 55 BST) at SCARBOROUGH UK.
As in 2011, the moon’s umbra misses the earth completely; the deepest partial eclipse taking place in northern Siberia. The magnitude of partiality in Cornwall is 16%, increasing as one goes further north and east. In London 26% of the sun is covered; in Hull 30%, whilst in Aberdeen almost 34% of the solar disc is covered by the moon. The deepest partial eclipse visible from the UK, with a magnitude of 40%, may be witnessed from the Shetland Islands, where first contact takes place a few seconds after 09h00. Second contact, when the moon leaves the sun’s disc, is due to take place at 10h 56 UT
(Remember, never to look at the Sun directly, as this could blind you; instead peoject its image onto a screen !)

SCARBOROUGH, NORTH BAY. Display of NOCTILUCENT CLOUDS during the late evening, ofJune 21, six hours after the Summer Solstice, in 2019: A beautiful Image courtesy of @FeelBetter2day Thanks Linda !. Noctilucent clouds are thin veil like clouds of ice crystals in the upper atmosphere, visible at this time of year in the northern sky. they are lit by the Sun which is not far below the northern horizon now.

JUNE 10: ANNULAR SOLAR ECLIPSE (PARTIAL from UK). Lovely image of the partially eclipsed Sun taken by Maurice Bradwell, from Wakefield West Yorkshire. Thanks Maurice!
