Attached find a lunar libration summary chart for lunation 1079 (3-15 to 4-13).  Note the very good 1st quarter altitude imaging opportunity.  Lunar altitudes are greater than 60 degrees just after astronomical twilight between 3-23 to 3-26 with the terminator sweeping W2 degs to W51 degs. http://fisherka.csolutionshosting.net/astronote/libration/Latest.jpg Historical charts are available in directory: http://fisherka.csolutionshosting.net/astronote/libration/ Similar charts can be found in the BAA Lunar Section Circulars archived at: http://www.baalunarsection.org.uk/circulars.htm Clear Skies - Kurt
