Summary
----------------------------------------------------------------------
clear and markedly colder night with frost and below freezing temps after midnight. managed to squeeze in two blocks for 2011-3-UW_DC-001 before the humidity got too high. did some closed-dome F-P tests afterwards. the sharp drop in temperatures apparently upset the etalons. they are definitely in a different state from a couple nights ago and the MR etalon would keep overloading unless i tweaked the manual fine settings down a little bit (from 600 to 560).
