2014 RASC Handbook Events

Updated 2013-08-11

Noteworthy events (marked in bold type in the main table on the next 2 pages):

Jan. 21:  PPM 153294 = SAO 56308 = TYC 0184-02239-1, spectral type (sp.) G5, a double star whose 11^th-magnitude companion is 10.4² away in Position Angle (PA) 22°. The companion will not be occulted.

Jan. 27: A 2006 occultation of (602) Marianna showed that it might be a contact binary. Omicron Geminorum = SAO 60247 = HIP 37265, sp. F0; it may be a close double star. The occultation occurs in daylight southwest of the Dakotas.

Feb. 1: A 2009 occultation of (234) Barbara seen in Florida showed that the asteroid is likely a contact binary.

Mar. 19: A 2011 occultation showed an unusual shape for the M-class (metallic spectral signature) asteroid (135) Hertha.

Mar. 20: Alpha Leonis = Regulus = SAO 98967 = HIP 49669, spectral type B7V, is the brightest star ever predicted to be occulted by a sizeable asteroid in North America. IOTA plans a major effort for the event, including plans to develop an app that could be used by thousands of cell phone users to help observe it. Regulus spins so quickly that its poles (1.25 milliarcseconds, or mas, apart) have 5 times the surface brightness as the equator (diameter there 1.65 mas). In 2005, Dunham video recorded a nearly grazing occultation of Regulus by the asteroid (166) Rhodope that occurred in Spain. That did not reveal Regulus’ close companion, possibly a white dwarf with a tenth of the primary’s mass and about 15 mas from the primary; the secondary star may be more than 100 times fainter than the primary. Regulus also has an orange dwarf companion, 8.2-mag. SAO 98966 177² away in PA 307°; Erigone will miss that star by about 10² 8 hours later.

Apr. 13: Venus’ 20² disk will be 60% sunlit. Only the dark-side reappearance can be seen. SAO 146220 = HIP 111820, sp. F8.

Jun. 9: Venus’ 13² disk will be 80% sunlit. Only the dark-side reappearance can be seen. SAO 93087 = HIP 12869, sp. A0.

Aug. 13: Normally we don’t include occultations of stars this faint, but Pluto’s moon Charon is of special interest for the New Horizons spacecraft flyby in July 2015. Charon will be 1² east and a little south of Pluto. (Not Included Below)

Sep. 13: Saturn’s moon Rhea will be just over 1¢ east of the planet. SAO 159034 = HIP 74007, sp. F2.

Sep. 15: SAO 129037 = TYC 4674-00425-1, sp. G5. A 12.6-mag. companion 35² away in PA 354° will not be occulted.

Oct. 2: (250) Bettina is an M-class asteroid that might support an unusual shape.

Nov. 8: SAO 75737 = TYC 1231-01670-1, sp. G0. A 10.4-mag. companion 17² away in PA 119° will not be occulted.

Nov. 13: (85) Io is the asteroid, not Jupiter’s moon also named Io. SAO 138490 = TYC 4938-00817-1, sp. F8.

Nov. 20, (3) Juno: It is unusual for a star this bright to be occulted by such a large asteroid; IOTA plans a special effort to observe it, in southern Canada and northern New England. SAO 117176 = HIP 43357, sp. G5.:

Dec. 11: (125) Liberatrix is an M-class asteroid that might support an unusual shape.
