Brent Tully, Institute for Astronomy, University of Hawaii, 2680 Woodlawn Drive, Honolulu, HI 96822, USA Daniel Pomarede` Institut de Recherche sur les Lois Fondamentales de l'Univers, CEA, Universite' Paris-Saclay, 91191 Gif-sur-Yvette, France Romain Graziani University of Lyon, UCB Lyon 1, CNRS/IN2P3, IPN Lyon, France Hel´ ene` M.

Shaya University of Maryland, Astronomy Department, College Park, MD 20743, USA ABSTRACT Cosmicflows-3 distances and inferred peculiar velocities of galaxies have permitted the reconstruction of the structure of over and under densities within the volume extending to 0:05c. This study focuses on the under dense regions, particularly the Local Void that lies largely in the zone of obscuration and consequently has received limited attention. Major over dense structures that bound the Local Void are the Perseus-Pisces and Norma-Pavo-Indus filaments sepa- rated by 8,500 km s−1. The void network of the universe is interconnected and void passages are found from the Local Void to the adjacent very large Hercules and Sculptor voids. Minor filaments course through voids. A particularly interesting example connects the Virgo and Perseus clusters, with several substantial galaxies found along the chain in the depths of the Local Void. The Local Void has a substantial dynamical effect, causing a deviant motion of the Local Group of 200 − 250 km s−1.

Er ist nicht im Optischen, sondern nur als Infrarotquelle zu erkennen. Er emittiert in Polrichtung einen hellen Jet aus ioni- siertem Gas, beleuchtet einen ausgedehnten Reflexionsnebel, und regt die Herbig-Haro-Objekte HH 28 und HH 29 zum eigenen Leuchten an.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract A 3-D shape model of the sixth largest of the main belt asteroids, (704) Interamnia, is presented. The model is reproduced from its two stellar occultation observations and six lightcurves between 1969 and 2011. The first stellar occultation was the occultation of TYC 234500183 on 1996 De- cember 17 observed from 13 sites in the USA. An elliptical cross section of (344.6 ± 9.6 km) × (306.2 ± 9.1 km), for position angle P = 73.4 ± 12.5˚ was fitted. The lightcurve around the occulta- tion shows that the peak-to-peak amplitude was 0.04 mag. and the occultation phase was just be- fore the minimum.

The Terms of Reference and membership for WG Star Names (WGSN) are provided at the IAU website: https://www.iau.org/science/scientific_bodies/working_groups/280/. ​ ​ ​ WGSN was re-proposed to Division C and was approved in April 2019 as a functional WG whose scope extends beyond the normal 3-year cycle of IAU working groups. The WGSN was specifically called out on p. 22 of IAU Strategic Plan 2020-2030: “The IAU serves as the ​ internationally recognised authority for assigning designations to celestial bodies and their surface features. To do so, the IAU has a number of Working Groups on various topics, most notably on the nomenclature of small bodies in the Solar System and planetary systems under Division F and on Star Names under Division C.” WGSN continues its long term activity of researching cultural astronomy literature for star names, and researching etymologies with the goal of adding this information to the WGSN’s online materials.

    2011 HP: a Potentially Water-Rich Near-Earth Asteroid. Teague, S.1, Hicks, M.2

    2011 HP: A Potentially Water-Rich Near-Earth Asteroid. Teague, S.1, Hicks, M.2 1-Victor Valley College 2-Jet Propulsion Laboratory, California Institute of Technology Abstract Broadband photometry was obtained to provide data on 2011 HP, a Near-Earth Object (NEO) discovered April 24, 2011. Our data was collected over a series of three nights using the 0.6 m telescope located at Table Mountain Observatory (TMO) in Wrightwood, California. The data was used to construct a solar phase curve for the object which, along with our measured broadband colors, allowed us to determine that the object most likely has a low albedo and a surface composition similar to the carbonaceous chondrite meteorites, which tend to be water-rich. 2011 HP appears to have a Xc type spectral classification, determined by comparison of our rotationally averaged colors (B-R=1.110+/-0.031 mag; V-R=0.393+/-0.030 mag; R-I=0.367+/-0.045 mag) against the 1341 asteroid spectra in the SMASS II database. We assumed a double-peaked lightcurve and were able to determine a period of 3.95+/-0.01 hr. Assuming a low albedo as suggested by the solar phase curve, we estimate the diameter of the object to be ~250 meters, and given that the minimum orbital intersection distance (MOID) equals 0.0274 AU, we recommend that this particular meteorite be re-classified as a Potentially Hazardous Asteroid by the Minor Planet Center. Introduction Asteroid impact craters dot the surface of our Earth as a visual reminder of the ever-present possibility of collisions of space debris with our home planet.

Fornasier1,2, C. Lantz1,2, M.A. Barucci1, M. Lazzarin3 Abstract This work focuses on the study of the aqueous alteration process which acted in the main belt and produced hydrated minerals on the altered asteroids. Hydrated minerals have been found mainly on Mars surface, on main belt primitive asteroids and possibly also on few TNOs. These materials have been produced by hydration of pristine anhydrous silicates during the aqueous alteration process, that, to be active, needed the presence of liquid water under low temperature conditions (below 320 K) to chemically alter the minerals.

Measurements were compared with literature data, and particular deviations are discussed.
