Four Mg II clouds (W(2796)=0.14 Angstroms) have been detected along the line of sight of quasar HE0001-2340 at z=0.4523. Three of these clouds display properties that are normal for Mg II absorbers; however, the fourth cloud is extremely unusual. It contains Fe I, which is not known to exist in other extragalactic absorbers, as well as Mn II, Ca I, and Ca II. Its Mg II absorption line profile is also indicative of partial covering, with a covering factor of 0.6, implying an extremely small cloud size. We explore Cloudy photoionization models for two possibilities: a cloud with a covering factor of 0.6, and one of 1.0 (full coverage). We conclude that the only way to produce the Fe I observed in the system is by using the model with partial coverage, and show that such models produce a small cloud size, as consistent with this theory. This system was studied using resolution R=45,000 data UVES/VLT data from the ESO archive, and research was supported by the National Science Foundation under Grant AST-07138 and by the REU Supplement Program.
