THE MINOR PLANET BULLETIN OF THE MINOR PLANETS SECTION OF THE BULLETIN ASSOCIATION OF LUNAR AND PLANETARY OBSERVERS VOLUME 35, NUMBER 3, A.D. 2008 JULY-SEPTEMBER 95. ASTEROID LIGHTCURVE ANALYSIS AT SCT/ST-9E, or 0.35m SCT/STL-1001E. Depending on the THE PALMER DIVIDE OBSERVATORY: binning used, the scale for the images ranged from 1.2-2.5 DECEMBER 2007 – MARCH 2008 arcseconds/pixel. Exposure times were 90–240 s. Most observations were made with no filter. On occasion, e.g., when a Brian D. Warner nearly full moon was present, an R filter was used to decrease the Palmer Divide Observatory/Space Science Institute sky background noise. Guiding was used in almost all cases. 17995 Bakers Farm Rd., Colorado Springs, CO 80908 [email protected] All images were measured using MPO Canopus, which employs differential aperture photometry to determine the values used for (Received: 6 March) analysis. Period analysis was also done using MPO Canopus, which incorporates the Fourier analysis algorithm developed by Harris (1989). Lightcurves for 17 asteroids were obtained at the Palmer Divide Observatory from December 2007 to early The results are summarized in the table below, as are individual March 2008: 793 Arizona, 1092 Lilium, 2093 plots. The data and curves are presented without comment except Genichesk, 3086 Kalbaugh, 4859 Fraknoi, 5806 when warranted.

Kennedy, Via De Gasperi 20, 35043 Monselice, Italy Abstract The correspondence between Giuseppe Lorenzoni and Pietro Tac- chini covers the period from 1870 to 1905. Two hundred and ninety original letters written by Tacchini to Lorenzoni and 177 rough copies of letters by Lorenzoni to Tacchini are preserved at the Padova Observatory Archives. Their friendship, which started in 1870 during the expedition to the total solar eclipse in Sicily, as well as their astronomical ability, were of great impor- tance for many events in Italian astronomy during the second half of the 19th century. -

LIGHTCURVE ANALYSIS FOR TWO NEAR-EARTH 320ʺ/min during the close approach. The eclipse was observed, ASTEROIDS ECLIPSED BY EARTH’S SHADOW within minutes of the original prediction. Preliminary rotational and eclipse lightcurves were made available soon after the close Peter Birtwhistle approach (Birtwhistle, 2012; Birtwhistle, 2013; Miles, 2013) but it Great Shefford Observatory should be noted that a possible low amplitude 8.7 h period (Miles, Phlox Cottage, Wantage Road 2013) has been discounted in this analysis. Great Shefford, Berkshire, RG17 7DA United Kingdom Several other near-Earth asteroids are known to have been [email protected] eclipsed by the Earth’s shadow, e.g. 2008 TC3 and 2014 AA (both before impacting Earth), 2012 KT42, and 2016 VA (this paper) (Received 2018 March18) but internet searches have not found any eclipse lightcurves. The asteroid lightcurve database (LCDB; Warner et al., 2009) lists a Photometry was obtained from Great Shefford reference to an unpublished result for 2012 XE54 by Pollock Observatory of near-Earth asteroids 2012 XE54 in 2012 (2013) without lightcurve details, but these have been provided on and 2016 VA in 2016 during close approaches. A request and give the rotation period as 0.02780 ± 0.00002 h, superfast rotation period has been determined for 2012 amplitude 0.33 mag derived from 101 points over a period of 30 XE54 and H-G magnitude system coefficients have been minutes for epoch 2012 Dec 10.2 UT at phase angle 19.5°, estimated for 2016 VA. -

THE MINOR PLANET BULLETIN OF THE MINOR PLANETS SECTION OF THE BULLETIN ASSOCIATION OF LUNAR AND PLANETARY OBSERVERS VOLUME 43, NUMBER 3, A.D. 2016 JULY-SEPTEMBER 199. PHOTOMETRIC OBSERVATIONS OF ASTEROIDS star, and asteroid were determined by measuring a 5x5 pixel 3829 GUNMA, 6173 JIMWESTPHAL, AND sample centered on the asteroid or star. This corresponds to a 9.75 (41588) 2000 SC46 by 9.75 arcsec box centered upon the object. When possible, the same comparison star and check star were used on consecutive Kenneth Zeigler nights of observation. The coordinates of the asteroid were George West High School obtained from the online Lowell Asteroid Services (2016).

CCD photometric observations of three main-belt 3829 Gunma was observed on 2016 March 3-5. Weather asteroids conducted from the George West ISD Mobile conditions on March 3 and 5 were not particularly favorable and so Observatory are described.
