Welcome!

You have landed on the home page of Robert Geofroy. 

I have worked all my life in education through secondary school, colleges and the university.  I am now living a life of "luxury" in retirement and can enjoy all those things which I never had time for when I was working-a little music, studying our indigenous languages, and being a just a little closer to nature. I still do my bit of teaching as it becomes necessary from time to time.

Astronomy has always been one of my favourite hobbies. Now that I have finally left the world of work  (retired)I have some time to enjoy the wonders of the sky above. My thing is naked eye astronomy. So I have no visual aids and only what comes into my eyes I see.
 
It is always good to know what you are looking at and to be able to tell an interesting story about the constellations and the stars. The ancient civilizations without all the modern aids that we have were able to. A night out under the stars is all you need to bring you back to reality!
 

 
One of my favGreat Nebula Orionouriite shots is the Great Nebula in Orion.  This is M42 a diffuse nebula. The "M" was for the comet hunter Charles Messier. Messier cataloged this object in his quest to ensure that he did not mix up these celestial objects with the comets. It can be viewed with a pair of binoculars or a small telescope. Of course, the better the instrument the better the image.
 

 
67PThe big news that has astonished me is the story of the spacecraft that is orbiting a the comet 67P.  The orbits of comets are highly irregular and so this is a feat of mathematical genius. The spacecraft is "Rosetta" and it is orbiting the comet 67P.The full report can be viewed here.
 


As we move through this wonderful month of August, there are four main meteor showers to look out for - the Eradanids, the Perseids, the Cygnids and the Leonids. There are also the Doradids and the Aurigids so there is no shortage of meteors. August is indeed a month to be outdoors watching for meteors.
 
The Perseids will be the "stars" to watch for. The Perseids are one of the most amazing meteor showers. This meteor shower results from particles of dust from the comet Swift-Tuttle as they impact the Earth's atmosphere.The Perseids are visible from July 17 through to August 24 and peak around August 12. The moon is new early in the month of August so it is at first quarter around the 12th. At any rate it is well worth while being ready to enjoy this treat. Last year, there were well over 100 meteors per hour from this shower.
 
Activities:
  • Use a start chart and plot the path of each meteor. Identify the  focus of the shower (point where the meteors are emerging from). Compare with your friend.
  • Have a look at Mammana's website and try your hand at some photography of the meteors.
 
This month, we can also track the paths of the planets Saturn and Mars in Scorpio. This should be a spectacle. If you are having a challenge finding your way around, you may want to register with Sky and Telescope and use their interactive star map. Alternatively, install the S&T app on your Android device. You might like to plot the position of the planets against the starry background and compare with your friend's plot.
 
Enjoy!

Before you go outdoors, read this. I am sure you won't be disappointed!
