August 26th, 2003
At the movie of Akutsu, the cloud of NPR should move with the rotation
and it understands it. As for the cloud of NPR, it finds that a center
is shifted from this image. There is a record like Frash in the image
of Frank J Merlillo but it thinks that this was made in the process of
the processing. When seeing the same frame, some places to be doing
the way of falling which is similar are seen.

天気予報では曇りのち雨でしたが、
日没後晴れ間が広がりだし、火星も
雲に見え隠れする状態で、21時半頃に
撮影が可能な状態になりました。
１回撮影したら西から近づいた雲に
隠されてしまいました。
今日もシーイングが極度に悪く火星像は
アメーバーの如くフニャフニャでした。

Good morning to all....
A brilliant reddish flash was recorded on these ASO images from Aug. 26, centered on the planet at nearly 06:56 UT; the scintillating bright red spot can be seen in all RGB images but is most prominent in Red and the combined RGB image; it is located on the southern perimeter of the dark Solis Lacus, just above center in the images.

Hi all
Here is another Mars image, this time also including UV data to give better
contrast to the clouds (in contrast to the double IR-blocked Blue filter, no
albedo features were seen in UV images). Also, a B-UV pseudo color image  is
also shown to depict this.
Time data is mid-exposure for each channel. IR=broadband near IR
(830-1000nm); UV= broadband near UV (320-390nm); B= blue astronomik type II
filter, stacked with astronomick IR-block filter. individual integrations
were 10sec for the B image, 15sec for IR and 60sec for UV. Original
sampling.   Steady skies...

Hi observers : last night I have seen the quality of the seeing passing from
very poor to fair or even fairly good in just a matter of minutes :-o. I
think however that because of my fear of the clouds I have adopted uncorrect
parameters for the RGB images which are too noisy.
The morning haze is very bright, however.

Planet's surface stills looks fairly clear in comparison to the previous night's image. I am now processing the images with the new version of Registax, Version 2.

Hello All!
Very intense blue haze on NPC and West side of the planet.

A possible flash near Solis Lacus?
Dear all
I have attached a montage of all my images of Mars on the 26th of August. Once again, there was a possible flash at 4:10 UT and 4:23 UT. All other images are seen with no flash. The location was at "10 o'clock " position of Solis Lacus. Also, Vic Palmieri had seen it too at 4:32 UT and his sketch is included with my montage. It looks pretty convincing that it was captured or something was there.
Please, let me know if this is reality. This montage is not posted yet on the website.

Hubble Space Telescope(2900mm fl=5300mm)

NASA's Hubble Space Telescope took this close-up of the red planet Mars when it was just 34,648,840 miles (55,760,220 km) away. This color image was assembled from a series of exposures taken between 6:20 p.m. and 7:12 p.m. EDT Aug. 26 with Hubble's Wide Field and Planetary Camera 2. The picture was taken just 11 hours before the planet made its closest approach to Earth in 60,000 years.
Many small, dark, circular impact craters can be seen, attesting to the Hubble telescope's ability to reveal fine detail on the planet's surface. One of the most striking is the 270-mile- (450-km-) diameter Huygens crater, seen near the centerof the image.
The two dominant dark swatches seen on this part of the planet are classical regions labeled by early Mars observers. The "shark-fin" shape to the right is Syrtis Major. The horizontal lane to the left is Sinus Meridani. One of NASA's Mars Exploration Rovers, named "Opportunity," will land at the western end of this region in January 2004.
The picture shows that it is a relatively warm summer on Mars, as evident in the lack of water-ice clouds at mid-latitude, and the receding southern polar cap. Ice on the rugged topography gives a somewhat ragged, scalloped look. Up north, at the top of the disk where it is Martian winter, a frigid polar hood of clouds covers the northern polar cap and surrounding region.
Even in the relatively balmy Southern Hemisphere, daytime highs are just above freezing in the Hellas impact basin, the circular feature near the image center. Hellas is nearly 5 miles deep (8 km). Hellas is like Death Valley ? except that Mars is much drier than even Death Valley. Having a diameter of 1,100 miles (1,760 km), Hellas was formed when an asteroid slammed into Mars billions of years ago. Many summer dust storms originate in this basin, though it is remarkably clear of dust in this Hubble image.
Mars and Earth have a "close encounter" about every 26 months. These periodic encounters are due to the differences in the two planets' orbits. Earth goes around the Sun twice as fast as Mars, lapping the red planet about every two years. Both planets have elliptical orbits, so their close encounters are not always at the same distance. In its close encounter with Earth in 2001, for example, Mars was about 9 million miles farther away. Because Mars will be much closer during this year's close approach, the planet appears 23 percent bigger in the sky.
This photograph is a color composite generated from observations taken with blue, green, and red filters. The resolution is 8 miles (12 km) per pixel.
