Hydrogen Alpha Sun – 22nd May 2016

by on May.22, 2016, under Astronomy Blog

The day started out with clear blue skies and sunshine, so straight out I went to capture some Hydrogen Alpha images. There were only a few small prominences around the limb, so I did a few close ups of the naked eye sunspot AR 2546 and a full disk before clouds started building up and we went out for a walk.

I experimented with tuning the telescope to get some detail in the spot, but Newton’s Rings were awful.

When we got back from our walk there were two layers of clouds, each moving in different directions making it extremely challenging.

However I did manage to get AR 2546 again and a white light image through my 80mm scope.

After a rest, two talks this week. Leicester & Cambridge.

by on May.21, 2016, under Astronomy Blog

After a few weeks of rest, I start going round to astronomy clubs speaking yet again.

I have two outings this week:

On Tuesday the 24th of May, I am at Leicester Astronomical Society.
They meet at The National Space Centre, Exploration Dr, Leicester LE4 5NS.
Meeting starts at 7:30pm.
I will be speaking on Digitally Enhancing Astronomical Images.
If you’re in the area, come along and say “Hello”.

On Wednesday the 25th of May I will also be speaking to Cambridge Astronomical Association as part of their introduction evening at the Institute of Astronomy, Cambridge.
I will be showing them how to obtain deeper wide angle images of the sky, using an un-tracked camera.

Will be good to meet up with these two clubs yet again.
Thanks to both for asking me back.

Mercury Transit – 9th May 2016.

by on May.11, 2016, under Astronomy Blog

I had no more spare holidays to take, so had to work the day of the Mercury transit. But I took my Ha solar scope into work so I could at least view the ingress of the planet at lunchtime.

Watching through the scope I could see the extremely small disk of Mercury just starting to bite into the Suns disk. Right by a bright prominence. It moved onto the disk much quicker than I remembered from the previous transit. That is an image that is hard wired into my hard disk upstairs and will live in the mind for a long long time. I showed a few people from work the transit from about half 12 BST, then packed up and went back to work.

When I finished work at 4pm, I dashed home and opened up the dome and started to take pictures. The skies had got a little bit hazy by this time, but I was determined to try. Clouds and thick contrails kept moving across the Sun’s face, spoiling many AVI files captured by my DMK camera.

All was well until a little after 6pm, when clouds finally thickened and the Suns disk and Mercury’s small silhouette finally disappeared from view.

A great day, with fine weather for most people across the country so most people saw some of the event.
Here are my results, which I am well pleased with, especially with the cloud interfering. See image at the bottom for the average conditions.

Transit of Mercury – 9th May 2016.

by on May.08, 2016, under Astronomy Blog

Tomorrow we will be able to witness a relatively rare event when a planet moves directly between the  Earth and the Sun so will be seen to move across the front of the Sun. In this case it is the planet Mercury. Only Mercury and Venus, being closer to the Sun can do this. Mercury is a small planet roughly the same size as our Moon.

This is a fairly rare event. The last one I observed was in 2003. The next one will be in November 2019, where most of it will also be visible from the UK after midday until sunset. After that we have to wait until November 2032.

Mercury will be visible as a very small black dot moving slowly across the Suns disk.

Simulation of the transit taken from the SPA Web site. 

The SPA have also produced a pdf file guide to viewing the event which can be downloaded from here, as well as a video guide to observing the transit by Prof. Lucie Green which is available here.

Do not attempt to view the transit WITHOUT using proper equipment. You can ruin your eyesight in an instant, so look out for somewhere where a local astronomical society are holding an outreach event to view it. If skies are clear, Bedford Astronomical Society will be opening The Piazzi Smyth Observatory from 2pm and Stanion Stargazers, Near Corby will be at Stanion Village Hall and North Essex Astronomical Society will be in Great Notley Country Park that afternoon.

The disk of Mercury is extremely small, so a telescope with proper filtration is required to view the event.

The event starts at 11:10 UT (12:10 BST) when the tiny disk will move on to the Suns disk.

Mid transit occurs at 14:57 UT (15:27 BST) when the disk will be central on the disk.

Mercury leaves the Suns disk at 18:42 UT (19:42 BST).

Full details of the circumstances of the transit are given on the Time&Date Web page: http://www.timeanddate.com/eclipse/transit/2016-may-9

Losing Comet 67P, but regaining the Sun.

by on May.04, 2016, under Astronomy Blog

With the success of my Rosetta & Philae talk, and being able to follow Comet 67P since I first picked it up last summer, it seems I am finally starting to lose this comet The brightness of the comet has now dropped to below 18th magnitude and it is getting increasingly difficult to image using my equipment from my light-polluted location and the increasing length of the day. Sad though I am to finally lose it, I got much more than I ever expected, and to capture it going past the Leo Triplet a few weeks ago was the tasty icing on a very luxurious cake. Still amazing to think that a probe is still orbiting this comets nucleus and another sitting dormant on its surface.

Comet 67P near the Leo Triplet.
67P-Leo_Triplet-20160406More comets like this please!

On a lighter note, despite the lack of dark skies now it is really nice to come home from work, sit in the garden and capture a few images of the Sun. There is a lot of activity around the limb at the moment. I also noticed a very faint prominence that was almost detached.

Soon be time to get out the barbie.

An Evening Celebration of Tim Peake’s Principia Mission.

by on Apr.24, 2016, under Astronomy Blog

On Friday the 3rd of June I will be hosting an exciting evening as a celebration of Tim Peake, our first “official” British astronaut, and his much publicised Principia Mission to the International Space Station (ISS).

Tim’s mission comes to an end on the 18th of June when, Tim, Russian cosmonaut Yuri Malenchenko and NASA astronaut Timothy Kopra return to Earth in their Soyuz capsule.
CelebrateTim

This educational family event will be held on Friday the 3rd of June from 7:00pm until 9:30pm at Chelveston Village Hall, Chelveston, Northamptonshire, NN9 6AT.

During the evening I will present  and demonstrate how they manage to launch a rocket up to the ISS, Tim’s background, selection, training and lots more, using presentations, demonstrations and wonderful animations and video footage. We will also look at the ISS and what Tim has achieved during his 6 month mission as it draws to an end.

What we do know for sure is that Tim and the publicity surrounding his mission has truly inspired all generations. I hope this evening will also inspire and encourage people, young and old to appreciate our place in the universe and help give them the drive to work hard to achieve their own ambitions. You might be very surprised to know that even Tim never expected to be selected for the mission when he filled in his original application. Just look what happened to him!

I am hoping to be able to bring you live images from the ISS on the night as Tim and his companions start to prepare to leave for home. This will, of course, depend on the particular circumstances of ISS broadcasts on the night.

Soft drinks will be available during a short interval. Donations to Crazy Hats Breast Cancer Appeal will be very much appreciated. This worthwhile charity raises valuable funds to help cancer patients right the way across Northamptonshire.

The landing of the Soyuz Spacecraft was scheduled to take place less than 2 days later in the early hours of the 5th of June, but has now been extended until the 18th. I will give everyone full details of Tim’s return date & time and forthcoming visible passes of the ISS on the night so you can watch his return online back home or go out and wave to him as he passes overhead before he comes home.

So please join me for this exciting evening in Chelveston and let’s celebrate Principia, Tim and UK spaceflight history being made.

Minimum age 10. Children under 16 must be accompanied by an adult.

Cost per person only £8.
Discounts apply if more than 1 ticket is booked.

Please book your place by clicking the links to Paypal below.
Please bring in your printed E Mail confirmation on the night.

Hillside Nursery’s Open Weekend

by on Apr.22, 2016, under Astronomy Blog

Just a reminder that this weekend 23rd & 24th of April, I am proud to be associated with Hillside Farm Nursery’s open Weekend.
I will be there all weekend, along with a number of other willing astro helpers, showing people the Sun in all it’s glory (clear skies willing) and will be giving away lots of fantastic goodies generously provided by The Charlie Bates Solar Astronomy Project and The European Southern Observatory including solar glasses (Needed to view the Sun safely), beautiful posters and DVD’s. Hopefully inspiring more people to take more of an interest in astronomy and the Sun.

I have also organised a Sun quiz and a hopefully getting visiting children to draw some fantastic astronomy related pictures.

The event is completely free and is organised annually to raise money for the breast cancer charity Crazy Hats, which helps supports cancer patients right the way across Northamptonshire.

As well as our awesome astronomy display, where we will be highlighting local astronomical societies, there will also be a display of vintage vehicles, bikes, tractors and steam engines as well as lots of local crafts and stalls.

It should be a brilliant weekend and hopefully will inspire lots of people and especially the kids to think about the Sun, it’s role in our energy supply and astronomy.

So hopefully I will see you there. Come along and say “Hello” and let’s all smile at the Sun.

Olney & District Historical Society – 19th April 2016

by on Apr.18, 2016, under Astronomy Blog

Tomorrow evening I will be taking Olney & District Historical Society on a wild trip across to the very edge of our observable universe.

I will be giving my Whistle-Stop Tour of the Universe (Hitch-Hiking on a Ray of Light) presentation to them.

So let’s hope that they strap themselves in and get ready for a journey that really is out of this world.
As it’s a historical society I have also added a historical twist into the presentation.

Of course, it’s really just a good excuse to show some beautiful images of our wonderful universe.

The society meet at the Olney Centre, High St, Olney, Buckinghamshire, MK46 4EF.
Meeting starts at 7:30pm.

If you’re in the area, come along, say “Hello” and enjoy the ride.

Comet PANSTARRS Meets The Owl and Pussy Cat.

by on Apr.16, 2016, under Astronomy Blog

Comet C/2014 S2 PANSTARRS passes close to two Messier objects during the coming week. Currently moving south through the bowl of The Plough, the comet will pass between the planetary Nebula M97, The Owl Nebula and the spiral galaxy M108 on the 18th, 19th and 20th of April.
The map below was produced from an image of the two objects I took in 2009. Unfortunately the sky is too bright in the UK to be viewed when centrally placed between the objects.
The almost full Moon will also hamper observing and imaging.
We will however be able to view it most all night.
I have marked the approximate position of the comet at the start and end of the night on the three days it is closest to the objects.
Happy hunting.

A Tail of Two Comets.

by on Apr.10, 2016, under Astronomy Blog

There are currently two reasonable bright comets in our skies at the moment.

Comet C/2014 S2 PANSTARRS is our first of our two comets.
This is currently located in a very well known area of the sky.

It is currently moving south straight through the bowl of The Plough, so it’s almost overhead as soon as it gets dark.
At about magnitude 10 it is visible in a modest telescope.
It passes between M97, The Owl Nebula and the galaxy M108 on the 19th and 20th of April.
The comet will fade slowly as it heads south.

The map below shows the comets path until the end of May.
Position shown at 1 day intervals. Click on map for bigger view.

Our second comet is Comet 252P LINEAR in the southern sky just before dawn. This comet is much more active than expected, exceeding all our expectations. At one point the coma was almost as big in apparent size as the Full Moon.

The comet is in the constellation of Ophiuchus and heading slowly northwards. It should fade as it recedes from the Earth and the Sun.

The map below shows the position of Comet 252P at one day intervals up until the end of May 2016. Click on map for bigger view.
