解説（安達）/ Comment by Makoto Adachi
Here is a mars report performed with the 127mm EDT refractor to get more stable images.
During the short session images get 7-8/10 at the best.
This allowed plot brightenings on mars against the main features.
The north cap was white bright,a thin haze close to the cap was spreading as notes on the sketch performed with the blue filter.
Over Thaumasia〓until Mare Sirenum,on Claritas,a clear streak was noted without filter use and with the blue filter,
this is quite strange having seen this on the calm moments mostly.
This needs a confirmation with a bigger aperture and calm images.
The south cap exhibited still a tiny whitish dot with Eridania close to on the terminator.

The seeing was again rather good but not quite as good as on the 14th April.
The view was much the same as the 14th April although a little more of the Mare Sirenum was visible.

NPC still visible,though not very prominent. Some atmospheric effects seem to be present,
e.g. in the deep south near the terminator,and around the equator on the preceeding side.

Bright white clouds were present in a series of patches over the peaks of Tharsis.〓
The northernmost patch (Pavonis) which was near the limb also showed〓a dark half toned patch to the west of the cloud,
just as Olympus Mons did the previous evening.
Olympus Mons showed no cloud this〓evening,just a dark half toned patch.
Another half toned patch in the vicinity of Propontis,and some morning mist corresponding with Elysium.
Also a hint of a band of cloud following the curve of Mare Cimmerum,just to the south of the Mare.
The NPC looked straight and white.
The SPH was bright towards the pole,with thin mist covering the regions south of Mare Cimmerium.
