Curtis Cross (the "other" Lunar X) - dates for 2012
« on: 12:49:09, 09 December, 2011 »
In my search for Werner's Lunar "X" dates I came across another optical feature that is visible each month on the moon, called the Curtis Cross.

It is not as obvious as the main Lunar X but something worth watching out for and imaging if you like this sort of thing (it's just gone on my bucket list !).

More details can be found here: http://ltvt.wikispaces.com/Curtiss+Cross

... and the dates and times for 2012 are:
