An Illuminated Letter "D" (lunar)


Recommended Posts

After a hard day "throwing" concrete slabs around For (Macavity's StarPad), I almost gave it a miss, despite clear skies. But now glad I relented as I was rewarded with a magnificant view of sunrise on the Sinus Iridum(?) - Rather like some vast illuminated-manuscript letter "D". <G> But I hadn't imagined that bright features projected so FAR into the darkened hemisphere... ;)

I did casually wonder how LONG it might take for the suns rays to progress along the floor of this feature... But then a nice hot bath beckoned! :(

Hi Chris, did you happen to catch The Moon Maiden? ;)

Here's a sequence i captured a number of years ago of sunlight slowly pouring over Montes Jura (the 'D' you saw). I regret not noting the times the frames were taken, but it took several hours. The terminator creeps along at 1/2 degree per hour at the lunar equator though, so it's understandably slower as you go towards the poles.

Hi Carol. Well, I'll certainly keep an eye open for her in the future. :D

Thanks for the sequence and thoughts. :p

But <thinking> as a previously only casual Lunar observer, it might be a useful key to "learning" the Moon. Find something (personally, and visually) interesting and take it from there... :p

Aside: Wahey! Just managed to re-locate my SECOND ever (and first serious!) Astronomy book: D.H. Menzel's "Field Guide to the Stars and Planets" (1966). But it does constain a rather appealing and useful PHOTOGRAPHIC Atlas to the Moon... Perhaps a job for the modern Laminater thingie. ;)
