2016 Noteworthy events

Dec. 13: Tanete: SAO 129589 = HIP 9177, Sp. A0. See the Jul. 13 event note about a possible satellite.

 

2017 Noteworthy events

Jan. 30: Venusís 30ļ disk will be 41% sunlit. Only the dark-side disappearance can be seen. SAO 146860 = HIP 117016, spectral type A0.

Mar. 11: SAO 80909 = HIP 46938 = HD 82670, sp. K5. The starís angular diameter of about 0.003″ should cause the star to disappear in 0.4 sec for a central event and longer for a near-graze, so it might be measured from video or other high-speed photometric observations. There will be partial occultation zones about 4-km wide at the path edges.

Mar. 28 & Nov 13: Kleopatra is the largest M-class asteroid and the most elongated large asteroid, about 4 times as long as it is wide. Radar observations around 2000 showed it to have a strange dog-bone shape, but subsequent occultation and adaptive-optics observations indicate that it may be essentially two triaxial ellipsoids joined end-to-end. Observations of this occultation will help resolve the true shape of this strange asteroid.

Apr. 10: SAO 184216 = HIP 79392, sp. A2IV. The star has a 10th-mag. companion 12" away in PA 185ļ that will not be occulted.

Aug. 14: SAO 59794 = HIP 34358 = HD 53686 = HR 2665, sp. K0. The starís angular diameter of 0.002″ should cause the star to disappear in 0.1 second for a central event and longer for a near-graze, so it might be measured with video. There will be partial occultation zones 6 km wide at the path edges. The path crosses central Nebraska a week before a solar eclipse there.

Aug. 23: SAO 164213 = TYC 5780-00308-1, sp. G. The path is over NW Missouri two nights after a total solar eclipse there.

Aug. 24: (849) Ara is an M-class asteroid that could support an unusual shape. Path in N Missouri three nights after solar eclipse.

Oct. 9: PPM 118757 = TYC 0644-00643-1. The star is the secondary star of a wide double; the 9.2-magnitude primary star is 19.8" away in PA 158ļ; it will not be occulted.

Oct. 21 & Nov. 14: Observations of an occultation in 2004 Apr. 18 show that (772) Tanete may have a satellite a few hundred km away.

Nov. 21 (849) Ara, Nov. 26 (110) Lydia, Dec. 4 (338) Budrosa, and Dec. 18 (161) Athor: These M-class asteroids are of special interest since they could support unusual shapes
