Solis Lacus
The eye of Mars is upon us. Solis Lacus was prominent along the central
meridian, Sunday night. Thanks to a break in the monsoonal cloud cover, I was able to observe the red planet at 06:10 UT on August 24. The seeing was middling, so I was limited to 247X in my 10-inch, f/4.5 Newtonian. Popularly referred to as the Eye of Mars, this roundish feature serves as the iris of the Martian eye. It is surrounded by Syria, Claritas, Thaumasia and Sinai, all lighter in tone than the dark Solis Lacus. Mare Erythraeum and Aurorae Sinus border to the east toward the preceding limb. Bosporus bridges the expanse from Mare Erythraeum to Pontica and Aonius Sinus to the south. A subtle finger-like albedo feature points from Aonius Sinus to the north and east. This is Araxes. A darker finger extends from Aurorae Sinus toward the central meridian to the west. This finger passes just north of Solis Lacus. Taken together, this conglomeration of dark and light markings forms the Eye of Mars. The South Polar Cap continues to diminish in size, but still blazes brightly white. Its dark collar has been exchanged for something less gaudy, a smoky gray ring which edges the frozen carbon dioxide wasteland. The North Polar Hood, a layer of clouds shrouding the polar cap, appears as a subtle brightening along the northern limb. Portions of Niliacus Lacus and Xanthe are visible immediately to the east. The remainder of the disk looks barren. If not for the rich fleshtone hue, it might remind one of the Earth's Moon. This is Mars at his biggest and best, the god of war reigning over the waning summer sky: http://hometown.aol.com/billferris/mars082503.html Regards, Bill Ferris "Cosmic Voyage: The Online Resource for Amateur Astronomers" URL: http://www.cosmic-voyage.net ============= Email: Remove "ic" from .comic above to respond |

Hi Bill,

People refer to this as the boring side of Mars but I think the subtle detail is wonderful. Popularly referred to as the Eye of Mars, this roundish feature serves as the iris of the Martian eye.

And isn't the northern part of the eye circle actually Valles Marineris?

Solis Lacus
Hi Bill,
I had my 10" out last night and the seeing was quite good at times. I couldn't help but notice that there was a "second" Solis Lacus next to the first one. Using Mars Previewer I think I got a good look at Juventae Fons. rat ~( ); email: remove 'et' from .com(et) in above email address |

HI Bill: The seeing was pretty darned good here, and Solis Lacus looked amazing in the C8....got a pretty good image of it too: http://skywatch.brainiac.com/planets/index.htm Nice detail, Rod. My efforts on Sunday were not as successful. Hope to try again tonight. Phil |

I swear on a stack of S&T: I'm going to be ready to make such fine photos the next time Mars is this close. There should be enough time to prepare, even for me. |
