LUNAR METEORITE DHOFAR 310: A POLYMICT BRECCIA WITH DEEP-SEATED LUNAR CRUSTAL MATERIAL. ... Introduction: Dhofar 310 is a new lunar highland meteorite found in the desert of Oman nearby Dh 302, 303, 305, 306 and 307. This is the first lunar meteorite that contains material derived from a deep location of the lunar crust. ... This is a fragment of spinel pyroxenite. ... The presence of spinel pyroxenite indicates that the rock contains lithologies excavated from deep units of the lunar crust. ...

R And S5/4.5e. S And SN (NGC 224). W And S7.5/1-e. X And S5/7-e. Z And The light curve is characterized by outbursts up to 4m with intervals of 10 - 20 years. In the intervals cyclic variations are observed with the mean period of 632d and variations with cycles of several days and Delta(m) ~ 0.1m - 0.5m. The spectrum is symbiotic, with features of a late M giant, narrow low-excitation emission lines (Bleq) and forbidden lines characteristic of highly excited nebulae. RR And S6/3.5e.
