Moon occults Pleiades tonight 2:25am to 5am MDT 8-14 Tonight, the Moon drives on deep into the Pleaides' center. Begins 2:25am MDT with occulation of 17 Tau Electra on the bright limb side. Moon alt 23 az 76.  Alcyone (eta Tau) is eclipsed on the bright limb at approx. 3:10am. Alcyone (eta Tau) egresses on the dark limb at approx. 4:10am below Mare Crisium on the west side (eastern lunar) limb. Ends with egress of Pleione (Tau 28) at approx. 5:05am.  Moon alt 53 degs az 104. Graze map by Rentz: www.curtrenz.com/1024l.hml Occultations egresses can be used to see very close binaries (via changes in brightness) that ordinarily are below the diffraction limit of your telescope, e.g 0.1" to 0.5".  E.g. Electra 17 Tauri 0.2" egress at 2:53MDT. The major ingresses and egresses for this observing opportunity (with UT times) are: Occultation prediction for SaltLakeCity UT from Occult 4 E.
