Hi all, here's an image of Mars taken under very good conditions. Syrtis Major can be seen in the middle of the image, with Hellas below it containing clouds. Elysium is setting at right, also covered in cloud.

¤····Subject: Mars + phobos + deimos + interloper

Received: 27 April 2016 at 08:21 JST

There was a transit of Phobos this morning, so I grabbed some images of it just before it crossed in front of Mars. Deimos was also in the frame and - to my surprise - so was another faint object on the opposite side of Mars which was approximately the same brightness as Deimos.

Here's an image showing Phobos just before it enters transit in front of Mars - you can see it at lower left very close to Mars, and also Deimos further out on approximately the same path. The unidentified object is at upper right.

I've also included a 2-frame animation showing a timelapse of 17 minutes, the interloper moves quite some distance relative to Mars over this time - at a guess I'd say it's moved about 5 arc seconds on a track almost perpendicular to the orbital plane of the moons.

Note: Phobos is not visible in the second frame of the animation as it's too close to Mars to see and lost in the glare.

Mars' proper motion over this timelapse is very small, much less than 1 arc second, I'm not sure the interloper could be a background star - anybody have any ideas? My guess is that it must be an asteroid but I'm happy to be corrected.

To be sure there were no hot pixels or camera artifacts present, Mars was moved constantly left<->right across the frame at slow speed during the captures. You can see the residual noise is spread out in this way, so anything that stays put must be signal and not noise.

Dear Minani-san,
I hope that you, your fellow recorders, and all CMO members are well. I am happy to be observing Mars once again.

I plan on making regular observations of Mars as the weather permits.

----------------------------------------------

Mars Observation (April 23, 2016)
I made a visual observation of the planet Mars on April 23, 2016 (05:30 U.T., CM 97.9°W) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain at 282x/352x (Explore Scientific 82° eyepieces showing much contrast and sharpness) showing a variety of albedo features surrounding the Tharsis ridge of the planet containing massive volcanoes and other interesting surface features. The North Polar Cap (NPC) appeared small and brilliant (10/10) with an outlier (most probably Cecropia) surrounded by a dark (3/10) collar. Mare Sirenum was visible as a wedge-shaped albedo feature towards the south on the central meridian (CM). The western half of Solis Lacus was visible towards the South-preceding (or morning) limb and appeared dark to dusky (3-4/10). An orographic (mountain-associated) cloud is visible over Olympus Mons towards the northwest following the CM. The western border of Mare Acidalium is visible towards the North-preceding limb. Cloud activity is visible over the Tharsis region as noted.
----------------------------------------------

The best of luck.

Comments:

Image of Mars in the early hours of 26-Mar-2016. The image was obtained near the same time as the day before, and therefore it is observed approximately the same region. Although the observation conditions were not the best, some superficial and atmospheric details are observed in the region of Tharsis and Arcadia, Olympus Mons and Tharsis Montes, with quite cloudiness in Chryse Planitia, a little higher than the previous day and with a displacement westward.

Dear Mr. Minami and Mr. Murakami,

I hope all is going well for you both. Please find attached an observation of Mars I took last night (23rd April) for the CMO. This is my first observation for this apparition, I am glad to be back at it again. 

I have attached each B, G, R image separately as well as the RGB image and have also attached a textfile with details of the observation. I am unsure of how you prefer to receive the images, if you have a particular way you would like me to send them please let me know.

The conditions were poor to moderate, but I still managed to achieve some detail. Note that as I have a 5" telescope I have to use eyepiece projection to achieve a good image scale. There was a very bright cloud over Elysium Mons and the Syrtis Major was well seen. Despite the conditions I hope you find the attached imagery useful. I look forward to better conditions and more images for the CMO. 

All the best.

Hi guys It was goodbye AR2429 hello AR2355 shown here in lesser seeing than of late, some fair moments though. 2529 was still pretty spectacular in Ha on the 17th. The sight of Jupiter near the moon on the 19th was one of those must image moments.

Seeing on screen was ok at f9 and I spent a couple of enjoyable hours out there in the dark for a change.

Dear all,
You can also see in the Maurice VALIMBERTI's beautiful animation on 17 April that the over 600km super crater Argyre Planitia and the easterly adjoining 230km "Happy Face Crater" Galle both frost-filled. In the latter part of the animation, along the southern limb of the red planet, this incongruous duo seems just like a blue-whitish frosty turtle moving east as Mars rotates! Both objects are quire well defined, that's the indication of the frost filled crater floors.

Hello everyone,

Please find attached my latest Mars images from this morning. The seeing was very jittery but Autostakkert did a very good job of sorting that out.

Dears,

Jupiter under acceptable conditions, which looks small to me after processing the ones from Pic du Midi.

IR is the most detailed :

Color image is not as good unfortunately :

Hi all,

Mars this morning under average seeing. Some intricate cloud detail over Tharsis region coming into view.

Hi all, here's a colour image of Mars from this morning. The north pole is visible at top left and clouds can be seen across the disk. The colours are better today, no terrestrial clouds interfered today so a good colour balance was easier to achieve than last time.

Very nice Clyde-lots of interesting detail in the boring face!

I often find pretty good seeing after the cloud has just cleared. The cloud will act as a radiative equalising blanket keeping the ground and air at similar temperatures. Take that away and the ground and scope then ‘see’ the cold night sky above which can be -20C to -50C. This when convection currents start to kick in and the local seeing then deteriorates.

Keep up the good work,

Hi all,

Mars this morning. It was almost totally overcast when I got up, but was rewarded as the clouds started breaking up, and I was pleasantly surprised that the seeing was reasonable. Possibly the "blandest" view of Mars, centred on the Amazonis region. In processing a few of the images that I took over a number of minutes, some of what I originally considered to be noise in the Amazonis region, turned out to be subtle albedo features. I will have a go at trying to put a GIF together. The two brightish features just south west of Olympus mons(Gordii Dorsum?) are quite clear. I am a bit intrigued by the row of dark dots just below the south polar hood. They aren't shown prominently on my globe or maps. Also by the darkening of the south polar limb. Is this purely due to the angle of Mars relative to the sun? I assume the dark feature cutting across the north polar region is Olympia Planitia? Looking forward to a bit more detail coming into view in the next week.

Best regards,

Hi Guys what a bumper 9 days that was. The superb spot AR2529 in both white light and Ha, is preceded of course by the last views of AR2526 and the fading AR2528. There was plenty of decent seeing to be had in the thin clouds too.

Looking at Gong this evening

2529 is putting on a spectacular show in Ha. I look forward to capturing that in about 9 hours time.

Best wishes

variable and interrupted often by clouds.

The north pole is visible at top left, Valles Marineris at lower centre,
and a number of cloudy areas across the disk.
