| Mars at same Ls but differents De, 1992 / 2006 by Christophe.P |

Hi all, here is a comparison I have made with one of Damian's images and one old HST's from the apparition of 1992-1993. Both images have been taken at the same season (only a few weeks before southern autumn/northern spring) but at very different "De" and the perspectives are interesting. At Ls 350 the seasonal NPC is fully formed and already nicely lightened by the Sun.
By looking closely where the very edge of the north cap lies, I think it's possibly seen on Damian's image.
Japanese 1992年のLs350゜のほとんど同じ様子を捉え、比較してみました。Deが異なりますが、北極冠のエッジが同様でたいへん興味深い。 ダミアンピーチの画像でも同様に(北極冠のエッジが)見えているようです。 (池村)１９９２年頃は、私たちはスケッチか、フィルム撮影をしており、これほどの画像は得られませんでした。 [Christophe.P (Bruz City,France)]
