Comet Lovejoy C/2014 Q2 is coming.

by on Dec.14, 2014, under Astronomy Blog

Comet Lovejoy C/2014 Q2 is heading northwards. Currently located in the constellation of Puppis, it is heading towards Columba and Lepus.By the 22nd of the month it should just about be visible from the UK. Currently estimated at just under 6th magnitude, it is almost a naked eye comet already, and should get brighter.

As it heads northwards it passes close to the globular cluster M79 in southern Lepus on the 28th of December.

The comet will head northwards passing to the west of Orion the second week of January, brightening all the time. On the 7th of the month the comet is at its closest to the Earth. The comet should be at its brightest for a week either side of this date.

By the middle of January the comet will be to the west of Taurus, passing through the Bulls legs.

On the 19th of January the comet will be almost exactly due west of The Pleiades Star Cluster.

By the end of January the comet will be to the east of Triangulum, reaching perihelion on the 30th. It’s intrinsic brightness should increasing as it recedes from Earth.

It will pass very close to Gamma Andromedae (Alamak) on the 3rd of February.
The comet will have faded somewhat by then as the distance from Earth increases.

The pace of the comet slows down as it heads further north its brightness fading all the time.

It will pass close to Delta Cassiopeia on the 16th of March.

It spends the next couple of months heading northwards, passing close to Polaris on the 30th of April and then takes a long time to pass close to Beta UMi (Kocab).

My New Rosetta Talk

by on Nov.23, 2014, under Astronomy Blog

I have just put in the finishing touches to my new Rosetta talk.

Rosetta & Philae: From Concept to Reality.

RosettaTalk

My new talk outlines the how the probe got to where it did, the missions accomplishments to date and relives the excitement on the day of the Philae landing.

Of course, the mission is nowhere near finished, and will go on until the end of 2015, so more info will be added as it released by The European Space Agency.

Get your local astronomical society to book me now.

Talk to Coventry and Warwicks Astro Soc.

by on Nov.15, 2014, under Astronomy Blog

I talked to Coventry and Warwicks Astro Society last night, enthralling them with my attempts to process colour images from the red and blue sensitive plates from the Palomar and Southern Sky Survey’s.

PalomarTalk

They looked after me well and there was a lot of questions and looking at the plates after my talk.

I had a very enjoyable evening.
It’s evenings like this that remind me why I do these talks.

Many thanks to everyone at the society for making me welcome.

Rosetta – Philae Landing Webcast.

by on Nov.11, 2014, under Astronomy Blog

The excitement is building for The European Space Agency’s (ESA) comet lander Philae.

The Rosetta lander Philae is due to land on Comet 67P/Churyumov-Gerasimenko on Wednesday the 12th of November.

Philae has been powered up and the landing program data has been uploaded to it.

All is now set for this exciting landing on the comet’s surface.

It will be released from Rosetta and will take 7 hours to reach the comet’s surface.

Confirmation of a successful landing should come with a signal which should be received just after 16:00h GMT on the 12th.

The ESA have organised a Philae Landing Webcast which will be available here:.
www.esa.int/rosetta or http://new.livestream.com/ESA/cometlanding

So take your ringside seat and watch as this unique event unfolds.

The key moments on Wednesday will be:

06:00 – Rosetta delivery manoeuvre.
07:35 – Final Go/No go.
09:03 – Philae separates from Rosetta.
09:43 – Loss of Rosetta signal during post-delivery manoeuvre.
10:53 – Regain signal from Rosetta.
11:59 – First descent data.
16:02 – Predicted landing time.
17:35 – Expected receipt of first 360 deg panorama.

All times are UTC (GMT), Earth received time.
(Events at the spacecraft happen 28 minutes earlier).

A few Astronomy images taken from The Seychelle’s

by on Nov.05, 2014, under Astronomy Blog

We went on a trip to The Seychelle’s staying on Bird and Cerf Islands.
No lights on Bird at all, as it disturbs the birds, so the Milky Way looked fantastic.
Being 5 degrees south of the Equator I was able to view a big portion of the southern sky I didn’t know.
I got up early one morning so that I could view the two Magellanic Clouds low in the South. Marvellous!
So I just had to do some Astronomy images taken from The Seychelle’s.
It’s a tough life, but someone’s got to do it…
