Mystery streak on Mars

Post by brian livesey »

A dark streak has appeared near Arsia Mons and is telescopically visible. See today's www.spaceweather.com

Thanks Brian, there's a challenge for this evening! :D

Clear sky is forecast here, and from 21:30 onwards the streak will be facing us, albeit to one side. It is nicely positioned by three in-a-row volcanos, but whether it can be discerned at the eyepiece is highly questionable.....>

"Because of the obscuring effects of the Earth's atmosphere, even the best groundbased telescopes usually can resolve features no smaller than about 300 kilometers across when Earth and Mars are closest to one another." The Red Planet: A Survey of Mars. Lunar and Planetary Institute.

May as well have a look, anyway... :)

Maximillian used his 355mm Newtonian and Baader RGB filters AS1290mm to make his visual discovery of the streak Nigel. Seeing was 6-7/10.

It's not clear to me from the spaceweather report that the streak can be seen other than on images (?)

Hello Brians, there was certainly no sign of it in my telescope last night, despite its claimed length of 600km. Too faint, I assume
