Mars in 2005/6 Home

The simulations on the right are from Mr. T. Ikemura and show Mars as it was expected to be seen at the date and time indicated. I am indebted to Mr. Ikemura for permission to use these images.   Mr. Ikemura's images are shown with north at the top.  Most of my images are not exactly north at the top; generally they are rotated through a small angle.


And finally (maybe) Mars on the evening of 11th January 2006.  Mars was 130.2 million Kilometres (0.870 AU) from the Earth and subtended an angle of only 10 seconds of arc.
Three weeks later and Mars has receded another 30 million kilometres and now subtends only 10 seconds of arc.  A very small object but a few surface details are still visible.

Only nine days later than the image below, but now Mars is over a hundred million kilometres away and subtends only 13 seconds of arc.

Mars on the evening of 10th December 2005.  Mars was 91.7 million Kilometres (0.613 AU) from the Earth and subtended an angle of 15 seconds of arc.
Mars is receding from the Earth and so its angular size is decreasing making the surface details more difficult.

Mars on the evenings of 16th and 17th November 2005.  Mars was 74.1 million Kilometres (0.496 AU) from the Earth and subtended an angle of 19 seconds of arc.
I have put the pictures from these two days together because I think it is interesting to compare the pictures taken almost exactly 1 day apart.  The later (upper) image appears displaced slightly to the west (left) compared to the earlier one.  This is because Mars rotates west to east slightly more slowly than the earth does, so a day later we see almost, but not quite exactly, the same side of Mars.

Mars on the evening of 12th November 2005.  Mars was 72.0 million Kilometres (0.481 AU) from the Earth and subtended an angle of 19.5 seconds of arc.
Although Mars is drawing away for us now, this is one of my best images in visible light, but unfortunately I didn't do the infra-red image until an hour later by which time the seeing had deteriorated significantly.

Mars on the evening of 4th November 2005.  Mars was 69.9 million Kilometres (0.467 AU) from Earth and subtended an angle of 20 seconds of arc.
These pictures were taken only 17 hours after the ones below;  that is just under 3/4 of a Martian day, so here we see a different view of the planet.  I do believe that the vague white dot near the top of the IR image is Olympus Mons, the largest volcano in the solar system.
Unusually, I captured the IR image here in colour mode, but I adjusted the colour sensitivity of the camera to be as near as I could the same in each channel, so the image appears, as it should, in monochrome.
(I'm not sure what went wrong with the colour picture; it is far too blue for the "red planet".)

Mars on the morning of 4th November 2005.  Mars was 69.8 million Kilometres (0.466 AU) from Earth and subtended an angle of 20 seconds of arc.
I'm rather pleased with these pictures as I was not expecting a clear night that night and awoke to find Mars shining brightly in the south-western sky.  Also this is not a good direction for me but Mars was shining through a gap in the trees caused by my neighbour removing an old ash tree recently.  So this was all done in rather a rush.

Mars on 22nd October 2005.  Mars was 70 million Kilometres (0.468 AU) from Earth and subtended an angle of 20 seconds of arc.
Mars is a strange object for imaging.  The conditions were far from perfect;  indeed I was not expecting clear skies that night and the images were made rather quickly before the forecasters became right (and Mars was rather low in the sky at 30°).  Even so the IR image is one of the best I have ever obtained, and the visible image one of the worst.  The clouds returned before I could try repeating the image in the visible.

Mars on 10th October 2005.  Mars was 74 million Kilometres (0.495 AU) from Earth and subtended an angle of almost 19 seconds of arc.
Mars is getting closer, and brighter.  I'm disappointed with these images.  I'm not sure why they are not better.  For the coloured image, I balanced the colours during capture just as I did last time;  in this picture I also adjusted the colours slightly in Registax using the sliders, to align the peaks of the histograms for the three colours.  (Click on the image to see what it looked like before this adjustment, and click again to get back here.)

Mars on 050928 Mars on 28th September 2005.  Mars was 80 million Kilometres (0.536 AU) from Earth and subtended an angle of over 17 seconds of arc.
I balanced the colours at the camera by using the RGB version of the brightness meter in K3CCDTools and adjusting the sliders until the three bars were about equal.  I think the resulting image is a little blue.  However the skies were very clear and the exposures are significantly less than on the previous night.

Mars on 050923 Mars on 23rd September 2005.  Mars was now 83 million Kilometres (0.557 AU) from Earth and subtended an angle of almost 17 seconds of arc.
I balanced the colours better here, but the IR image is not as good as usual. I'm not sure why, but my exposures are longer than they were last time, so I think there must have been some high cloud in the way.

Mars on 050908 Mars on 8th September 2005.  Mars was now 94 million Kilometres (0.626 AU) from Earth and subtended an angle of 15 seconds of arc.
My previous pictures have had no blue content.  I have raised the sensitivity of my camera to blue light for this picture, and maybe there is a little too much.  I wonder if this is how Mars will look if ever man terraforms it.  I took pictures with various settings of the colour sliders in the camera settings and the results may be seen by clicking on this image.

Mars on 050831 Only two days later, but a better picture.  Mars had crept a little closer and was 99 million kilometres (0.666 AU) away from us and subtended an angle of 14 seconds of arc.
The south polar cap is very small but can just be made out.  It is high summer in the southern hemisphere of Mars so the polar cap is expected to be small.

Mars on 050829 Mars continues to get closer.  At this time Mars was 101 million kilometres (0.677 AU) away from us and subtended an angle of 14 seconds of arc.
I only have an IR image;  The sky was beginning to lighten and the seeing was not good so I did not take a colour picture.

Mars on 050816 Mars at this time was about 84% illuminated, which is almost as small a phase as we ever see.  Mars is getting slowly closer as the Earth catches up with it.  At this time Mars was 114 million kilometres (0.762 AU) away from us and subtended an angle of 12 seconds of arc.

Mars on 050804 Mars on 4th August 2005 was 121 million kilometres (0.781 AU) away from us and subtended an angle of 11 seconds of arc.
This was my first attempt of the new season.  There was a lot of high cloud about that morning and by the time I captured this image the sky was lightening significantly.
I have shrunk Mr. Ikemura's picture to match mine in size.
