Seeing 8 out of 10. Very steady seeing. Warm, still air just before a front moving in. Lots of detail, Sinus Sabaeus very apparent, including the "hooks" coming off the north side. Argure, a bright spot in the south appeared to touch, or come close to touching the south polar cap. Possible clouds in the north following edge, near Mare Acidalium. No additional detail seen with W47 filter.

Hernandez at the Palermiti Observatory on June 13, 2001 (opposition date) at 02:15 UT using a unique 4-inch (10.2-cm) off-axis reflector (very high definition and contrast) and a Wratten 23A (light red) filter. Elysium was prominent (8.5/10) following the CM flanked by a darkened (3/10) Trivium Charontis-Cerberus I-Phlegra complex to the east (preceding) and a dark (3/10), elongated Hyblaeus Extension towards the west (following). Cebrenia to the north appears dark to dusky (3-4/10). The North Polar Cap (NPC) is not visible, but an extremely bright (9/10) haze is noted over the north polar limb. Some dusky to dull (4-5/10) albedo features over Panchaia are noted south of the north polar haze. Mare Cimmerium, Syrtis Minor and Mare Tyrrhenum are visibly dark (3/10) towards the south polar limb north of an extremely bright (9/10) south polar haze (SPH). Extremely bright (9/10) morning (MLH) and evening (ELH) limb hazes are noted as well. Carlos E. Hernandez (A.L.P.O. Mars Section)

This design is described on the Internet Telescope Exchange web site (http://www.burnettweb.com/ite/index.html) "The design consists of a spherical concave primary mirror with a sub-aperture meniscus corrector lens and a spherical secondary mirror both held in a baffled cell which is attached to the aperture end of the tube with a three vane spider (see image above). The sub-aperture meniscus corrects for spherical aberration and coma and fully compensates for longitudinal chromatic abberation with the help of the secondary mirror which is mounted immediately behind the meniscus. Because the meniscus and the secondary are made of the same substrate, secondary color in the system is minimal. This design yields images that are comparable to those generated by the Maksutov-Cassegrain system and are far superior to those generated by the popular mass produced Schmidt-Cassegrains." This observer has had the opportunity to observe through many high-quality specialized instruments, but this is among the finest in it's aperture-range and class. Having used a quality 8-inch (20-cm) f/10 Schmidt-Cassegrain for many years I can honestly state that the definition and contrast exhibited by this instrument is far superior. I heartily recommend this instrument to any serious planetary observer or imager. Notes: 07:40 UT (left image): An observation of Mars made using a Wratten 23A (light red) filter on June 13, 2001 (opposition date). The North Polar Cap (NPC) is visible as an elliptical, and brilliant (10/10) towards the north polar limb. Utopia (3/10) and Dioscuria (4/10) are visible towards the northern limb. Syrtis Major is prominent (3/10) on the CM and appears to be separated from Mare Tyrrhenum (3/10) by a thin, bright (7/10) strip (Crocea). Tritonis Sinus is visible projecting from the south-preceding limb with Hesperia (7/10) following it. Hellas was visibly bright to very bright (7-8/10) towards the southern limb and is bisected by a thin, dusky (4/10) strip (Peneus?). Mare Hadriacum (3/10) is visible over the eastern (preceding) edge of Hellas. Hellespontus is visible a dark (3/10) strip extending between Syrtis Major and Mare Australe towards the south-following (Sf) limb. Mare Australe is visibly dark (3/10) adjacent to the SLH. Sinus Sabaeus (3/10, preceding (or eastern) half) is visible towards the Sf limb partially obscured by an extremely right (9/10) morning limb haze (MLH). An extremely bright (9/10) evening (preceding) limb haze (ELH) and southern limb haze (SLH) is visible as well. 09:00 UT (right image): An observation of Mars made using Wratten blue (38A) and 64 (blue-green) filters. Extremely bright (9/10) northern limb haze (NLH), morning limb haze (MLH, southern limb haze (SLH), and evening limb haze (ELH) were noted. A violet (or blue (W38A)) clearing of 2/3 was noted as well. Hellas appeared very bright (8/10) towards the southern limb. Carlos E. Hernandez (A.L.P.O. Mars Section)

The North Polar Cap (NPC) is visible as a small, brilliant oval along the northern limb. Elysium is prominent (8.5/10) preceding the CM with a dark (3/10) Trivium Charontis-Cerberus I-Phlegra complex to the east (preceding) of it and the Hybaleus Extension (3/10) to the west (following). Panchaia and Utopia appear dark (3/10) towards the northern limb. A small, elliptical, and dark (3/10) Nodus Alcyonius was noted towards the north-following (Nf) limb. Tritonis Sinus and Mare Cimmerium appear dark (3/10) towards the southern limb preceding the CM. A dark (3/10) projection was noted extending from the northern border of Mare Cimmerium towards the south-preceding (Sp) limb over the Aeolis-Zephyria region (Laestrygonum Sinus?). Syrtis Minor and Mare Tyrrhenum were visibly dark (3/10) following the CM connecting the a dark (3/10) Syrtis Major (eastern or preceding half) towards the following limb. Hesperia was noted as a bright to very bright (7-8/10) strip between Mare Cimmerium and Mare Tyrrhenum. Extremely bright (9/10) morning limb haze (MLH), southern limb haze (SLH), and evening limb haze (ELH) were noted as well. 06:30 UT (right image): An observation of Mars made using Wratten 38A (blue) and 64 (blue-green) filters at 06:30 UT (CM=3D274.8).

Hellas was visibly very bright to extremely bright (8-9/10) towards the southern limb appearing to connect to the SLH. Mare Tyrrhenum, Iapygia Viridis, and Syrtis Major were noted with a violet (or blue W38A) clearing of 2/3. Carlos E. Hernandez (A.L.P.O. Mars Section)

- 5/100 sec integration x 8 [best] images
- 6" Mak, 2x Barlow (eff F/24), so a little undersampled.
- Used an orange filter
- Temperature 5 degC
- Very steady/good seeing (rating?),
- Cresent moon setting in low in the west at the time
(I cannot remember exactly how old the moon was yest)
- Images taken from the Sydenham, Victoria (suburban skies)
The set of images taken were consistently of a good quality, which
indicates a very steady seeing conditions.
Comments from Maurice V: The dust storm around Hellas which has been
reported in the last few hours is also visible [in the image].
Comments from Roger Davis: Elysium sure stands out with Stymphalius
Lacus, and the definition of the bit (forgot the name) between Mares
Lammerium and Tyrrhenum is very obvious.
The best of a series from 40+ images (see note below) were selected, dark
calibrated and processed using AIP software (averaged, unsharp filtered etc).
Final [minor] touch-ups were done using Adobe Photoshop.

Seeing 6 out of 10. Very hot, extremely humid, very hazy. Classic Washington, DC bowl of soup weather. Very dim image due to
haze, so didn't even try to use filters. Solis Lacus quite dark, firmly attached to Nectar and Mare Erthraeum. Light area
between Eryth raeum and Achillis Pons, almost appeared as light/hazy clouds. Very faint markings near Arcadia.

Orange Filter used.
This was the best of 8 images out of only 10, as after that, the images
seemed to degrade and/or I was having probs picking the best focus.
Visible in this image appears to be what looks like a front line of the
dust storm building up across Mare Tyrrhenum/Syrtis Minor region. At this
stage of the storm, you can still make out half of Syrtis Major and
features around the Utopia region.
