July 11th, 2003
It is recording Carlos E.Hernandez when there is dust storm in the
south of Mare Sirenum(160W,-30) In the image of P. Clay Sherrod, it
is recording a light part near Electris(180W,-45). However, this
seems not to be dust storm. In the image of Ed Grafton, the
neighborhood of Eridania(215W,-45) seems to be dusty from Ausonia
(245W,-45). The crack of SPC which can be seen at the true side by
making Syrtis major(295W,+10) the front became conspicuous slowly.
Specifically, a conspicuous change isn't seen.

I have made an observation of Mars this morning under average to good seeing conditions (5-8/10).
The dust storm at this time was localized over Electris-Eridania with a thin segment visible along
the southern border of Mare Sirenum. I welcome any comments on my observation.

Date (U.T.): July 11, 2003
Time (U.T.): 06:30
CM: 138.1
Ls 219.3 (Northern Mid-Autumn)
De -20.5. Ds -15.4, k 0.92
Diameter: 18.4 arc-seconds
9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 248x, 282x, and 362x
Filters (Wratten): 23A, 30, 38, and 64
Seeing (1-10): 5-6 (moments of 7-8), Antoniadi (I-V): III (moments of II)
Transparency (1-6): 2-3 (Hazy)
Notes:
The South Polar Cap (SPC) appeared brilliant (10/10) with a thin, dark (3/10) core and a rift noted
over it's following half. The SPC appeared to be surrounded by a dark (3/10) collar (Mare Australe).
Mare Sirenum appeared prominent (3/10) over the CM with thin, dark (3/10) projections noted to extend
from it's northern border connecting to a dusky (4/10), thin albedo feature parallel to it. A thin
very bright (8/10) segment of the dust storm was visible along the southern border of Mare Sirenum.
Phaethontis-Electris appeared dull to shaded (5-6/10). Aonius Sinus-Phasis appeared as a thin, dusky
(4/10) wedge between the eastern (preceding) end of Mare Sirenum and a dusky (4/10) Solis Lacus.
Lunae Lacus appeared as a dusky (4/10) condensation along the border of an extremely bright (9/10)
evening (preceding) limb haze.The dust storm was visible over the south-following limb over
Electris-Eridania (at this time enhanced by haze as it has been reported to have weakened significantly).
The eastern (preceding) portion of Mare Cimmerium was visible along the following limb adjacent to an
extremely bright (9/10) morning (following) limb haze.
Tharsis, Memnonia, Amazonis, and Arcadia appeared bright (7/10). The Propontis complex and Phlegra
appeared dusky (4/10) adjacent to an extremely bright (9/10) northern limb haze. Trivium Charontis
appeared as a small, dark (3/10) condensation adjacent to a very to extremely bright (8-9/10)
Elysium with an apparent haze over it.
The best of luck in your own observations and imaging of Mars.

Very turbulent air this morning and I was lucky to get even this it seems;
some interesting features appearing in mid-latitudes.

Hi everyone : I have observed this morning 30 mn before the arrival of
clouds. The transparency was quite low however and the images have suffered
a bit from this.

Have been trying to catch an image for weeks but weather in Western Australian
has been continuous rain.  Hope attached image is of some use.
Needed to use an IR blocker and Minus Violet filter to remove the unfocused light
of the 152mm achromat refractor.
