Subject: ASO Mars - August 25 (#1 of 2)

 

Good morning to all...

This is the first of two attachments, as we are having a very slow ISP connection here on the mountain at this time.

 

This series of three Mars images of August 25 are taken about one hour apart and show the prominent Solis Lacus area, as well as a very nice fully-illuminated Olympus Mons; the peak of this volcanic cone is actually seen in the middle of the three images. Several very thin and high bluish clouds are noted, one very small one on the pr. side of the O. Mons.

This is perhaps the best, most incredibly accurate image of Mars that I have seen thus far. Truly beautiful and very revealing....thanks so much.

Subject: ALERT - Mars.....Bright Red Flash in Southern Solis Lacus

 

ALERT:

there is a remarkable RED flash on the southern perimeter, nearly centered in longitude, of the dark Solis Lacus maria on the morning of August 26, 2003. This feature was imaged at ASO at 0656 UT, nearly centered on the planet; differential color density analysis does reveal that this very bright scintillation feature is strong in the red region.

 

One of our most detailed Mars images to date, showing some very fine and thin blue clouds over the Tharsis plains (lower right) and the large volcano Olympus Mons coming into view with full solar illumination (lower right, bright circular feature). NOTE the very bright REDDISH flash in the southern edge of Solis Lacus

(top, above center).

Subject: Mars, Aug. 26 - Bright Flash in Solis Lacus

 

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.

Subject: Mars on its Closest Day, ASO, Aug. 27

 

Mars at its closest approach, diameter 25.1" arc; Magnitude -2.9 (!). Seeing conditions very poor with turbulent air and high intermittent cirrus clouds; heavy air with mosquitoes (actually heavy mosquitoes with a bit of air mixed in.....). Note the very faint high blue clouds continuing over the Tharsis region (see ASO images from previous morning). The very bright spot ("flare" of 8-26) is not seen in brilliance in this image, but the southern perimeter of Solis Lacus is turned eastward from direct view at this time; whatever the bright scintillating feature might be, it requires direct sunlight for maximum reflectance and visibility at this time.

Subject: ASO Mars, August 29

 

Still presenting a beautifully detailed surface - and continuing to do so throughout September, 2003 - Mars can now be seen in this image to be developing some high blue clouds streaks in the high northern latitudes (north is DOWN in ASO images...); you can see faint streaks of blue clouds very near the North Polar Hood (bottom) as well as south of that against the reddish plains of the Red Planet.

 

Note that the very high reflective "flash" or spot reported earlier continues in the Solis Lacus maria, southern perimeter; this is better seen on the 0633 U.T. image August 28, 2003; note the very prominent blue clouds streak traversing E-W over the southern regions of the North Polar areas; the later image reveals this to end abruptly.

Subject: Mars and the Arkansas Governor

 

Good morning....on Wednesday evening and Thursday morning, Clay and Patsy Sherrod were pleased to host the Governor Mike Huckabee (left in photograph) and First Lady Janet Huckabee of Arkansas. The Governor and his wife and entourage comprised of State Representative David Haak, and Arkansas Parks Commissioner Debbie Haak, as well as a security team from the Arkansas State Police came to Arkansas Sky Observatory to witness Mars on its closest approach.

 

Because of poor seeing conditions (....doesn't it always happen this way....?) Mars was not as impressive as it could have been, but we obtained images for them to return to Little Rock with as well as certificates from ASO as having "officially" observed Mars during this close apparition.

 

In addition to Mars, the Governor et al were treated to an actual astrometric measurement and imaging of comet C/2001 K5 (Linear) for submission to the Harvard MPC, CCD imaging of the Ring (Messier 57) and Dumbbell (M-27) nebulae, and a tour of the sky via the robotic Meade 16" telescope at the observatory.

 

We learned that the Governor and First Lady are avid skywatchers and are shopping for a Meade LX 90 for the Governor's upcoming birthday.

Very nice images Christophe....

I am reeling from the incredibly rapid shrinking of the SPC over the past week.....the image you provided surely demonstrates the remarkable recession of it, just since our bad weather moved in on August 29....

Subject: ASO Mars Images

 

Good morning to all...

Thanks to those who have inquired about not being able to access our Mars image library at this time and our apologies about the problems. We are having some technical difficulties with the ASO site which are being worked on at this time.

 

Although the data for each image is coming up we are having trouble with the image files and this will be rectified within the week; I will notify you when the images are once again accessible.

 

In the meantime, those on the ASO Mars list who receive regular attachments will continue receiving our daily observations, weather permitting (!)...

 

Thanks to all and keep those observations of the Red Planet coming.

Subject: ASO Mars - Fine night, Sept. 4

 

Mars in one of our finest images this apparition, exhibiting some fine detail in very damp but steady skies; some thin clouds seen north of Sinus M. and Sinus S.; note the interesting segmented portion of the SPC as it is now rapidly receding.

 

. . . . . . . .Date: Fri, 5 Sept 2003 05:09:59 -0500

Subject: Mars and South Polar Cap, Sept 5

 

Mars under very unsteady skies; however note the bright area (cloud) on the eastern edge (upper right limb), south of the equator. Very nice detachment now exhibited in the SPC and some cloud activity throughout equatorial areas.

 

. . . . . . . .Date: Sat, 6 Sept 2003 08:20:13 -0500

Subject: ASO Mars, Sept. 6

 

An image of Mars this morning with very unsteady air due to passage of cold front dropping temps over 38 degrees in a few hours. A bright Hellas is visible.

 

. . . . . . . .Date: Sun, 7 Sept 2003 02:36:28 -0500

Fubject: ASO Mars, Sept. 7....Polar Cap clouds

 

A very interesting view of Mars and the SPC, with an incredibly beautiful green-blue shearing cloud cutting E-W across the south polar cap; this can be seen clearly in both the RGB and Green image insets. Note also the high blue clouds on the eastern (fol.) terminator at right.

 

Poor seeing, but nice detail emerging nonetheless; most of the SPC is now sublimated with the rift evident from the Mountains of Mitchell; Hellas (northern portions) are quite bright.

 

. . . . . . . .Date: Mon, 8 Sept 2003 02:03:01 -0500

Subject: ASO Mars - Sept. 8, 2003

 

Mars under very good conditions and stable air; high haze capping steadiness of image. Note the very bright northern regions of Hellas and the small blue/white "popcorn" clouds throughout the southern regions of Syrtis Major, seen best in the full scale RGB image as well as in the GREEN image inset. (disregard reference on image to "S. Hellas"; should read "N. Hellas."
