Where to find Comet 67P This Summer

by on Apr.18, 2015, under Astronomy Blog

With the recent launch of the Rosetta ground-based campaign to observe comet 67P/Churyumov-Gerasimenko from April until December 2015, I thought I would publish some maps showing where we might be able to find Comet 67P later this summer.

The comet has already been recovered by imagers in Chile.
Realistically us observers based in the UK are unlikely to pick it up until mid – late July and onwards.

The comet will at this time be moving through Taurus and into Gemini. It will be visible fairly low in the early morning eastern sky. It should be about 12th even 11th magnitude at this time, and that’s about the brightest it will get, being somewhat around the Sun in it’s orbit
This map shows the path of the comet below as seen from Earth.

So it is in a very distinct and easy to find part of the sky. Mid-month sees the comet passing between The Pleiades and Hyades open star clusters and out through the horns of the Bull by the end of July .
On the 8th of August, just 5 days before perihelion, the comet passes straight through the small open cluster NGC2158. This is a smaller cluster right next door to the much bigger M35 (NGC 2168). It just skirts M35 a little while later.
This is shown in the map below.
So we have some very familiar and distinct markers to help us find this very interesting comet. It is certainly a unique opportunity to observe a comet with a space probe going round it that I certainly don’t want to miss.

Rosetta Ground-Based Campaign.

by on Apr.15, 2015, under Astronomy Blog

Amateur astronomers are being called on to take part in a Rosetta ground-based campaign to observe comet 67P/Churyumov-Gerasimenko from April until December 2015.

Click on this link for more details.

There is also a Facebook group dedicated to it.

Some dedicated observers have already recovered the comet now it has passed solar conjunction.

So there really is no excuses for not knowing where to look.

Lincoln Astronomical Society – 7th April 2015

by on Apr.08, 2015, under Astronomy Blog

Before my talk last night we were treated to a fine Sun Dog to the side of the observatory of Lincoln Astronomical Society.

LincolnAS

I did my talk entitled “In the Footsteps of Piazzi Smyth – Astronomical Adventures in Tenerife” to Lincoln Astronomical Society  last night.

AdvTenerife

There were about 40 people attending that evening and if the multitude of questions afterwards are anything to go by my talk went down very well indeed.
Many thanks to Lincoln Astronomical Society for giving me such a warm reception in their wonderful facilities.
I really enjoyed the evening, making the journey there well worth taking.
Hopefully they will have me back for another talk in the not too distant future.

Partial Solar Eclipse – 20th March 2015

by on Mar.20, 2015, under Astronomy Blog

It looked hopeless at the start of the partial solar eclipse as there was mist and thick cloud at work.
But, as the Moon started to encroach onto the Suns disk, the clouds started to break and the event was starting to be revealed.

We could easily see the Eclipse progressing throughout without the eclipse glasses and followed it right through to Maximum and beyond. Skies were almost completely clear by the end of the eclipse.

Despite the cloud and a few forgotten items, I did manage to get some images through my 80mm refractor.

In the original images you can see the profile of the Moon is not smooth and the mountains along the Lunar limb show up really well in silhouette.

A great way to spend time at work with the blessing of my boss.

Stonking!

Talks: Rosetta & Philae: From Concept to Reality.

by on Mar.17, 2015, under Astronomy Blog

Tonight I will be talking to Northants Amateur Astronomers.

Tomorrow evening I will be visiting North Essex Astronomical Society.

Both groups have booked me for my popular multi-media presentation,

Rosetta & Philae: From Concept to Reality.

RosettaTalk

Both groups feel like old friends now, as I have been to talk to each of them a number of times.

I am really looking forward to bringing the Rosetta & Philae, Comet 67P mission to life for them.

If you are in the area of these two groups on these evenings, do come along and say “Hello”.

Comet Lovejoy C/2014 Q2 and The Owl Cluster

by on Mar.10, 2015, under Astronomy Blog

Although fading, comet Lovejoy C/2014 Q2 is still (just) above naked eye visibility. Tonight it was passing close to the star cluster NGC 457 in Cassiopeia. This lovely cluster of stars is also known as The Owl Cluster. The field of view on my ED80 telescope was wide enough to easily get both objects in the same field of view.

I managed to get a reasonable image of both objects despite the thin cloud that spoiled the view somewhat. You can see some brightness around the cluster caused by the cloud interfering.

Comet Lovejoy continues to give.

Comet Lovejoy C/2014 Q2 – 2nd March 2015.

by on Mar.02, 2015, under Astronomy Blog

Comet Lovejoy C/2014 Q2 is still shining fairly brightly, now starting to approach Cassiopeia.

For a detailed map of the comets current position, see the last few pages of my Sky Diary.
http://www.eagleseye.me.uk/SkyDiary.html

The comet has sadly faded somewhat in the past few weeks and the light from the gibbous Moon is interfering somewhat.
But t I thought I would still give it a go now my throat and cough is much better. The comet looks less active with far less distinct streamers in the tail, but it’s still looking good with a reasonable tail and the nucleus is still bright enough for my telescope to auto-guide on it.

Picture saved with settings embedded.
I will enjoy watching this comet shrink away, especially once the Moon moves out of the sky in a week or so.

Sawtry Astronomical Society

by on Feb.25, 2015, under Astronomy Blog

Now almost recovered from the lurgie, I did my popular multi-media presentation “Rosetta & Philae: From Concept to Reality”, to Sawtry Astronomical Society last night.

RosettaTalk

This was my third visit to them in a year and they gave me a very warm welcome.

It was great to be back.

Once again this entertaining and interesting talk went down extremely well.

And as a bonus I even won some chocolates in their raffle.

I now have a rest now for a couple of weeks until I do the same presentation to Northants Amateur Astronomers on the on the 17th of March.
