The data, which are sufficiently scattered to yield gross thickness variations, are restricted to shallow maria with less than 1500-2000 m of mare basalts. The average thickness of b-asalt in the irregular maria is between 200 and 400 m. Multiringed mascon basins are filled to various levels. The Serenitatis and Crisium basins have deeply flooded interiors and extensively flooded shelves. Mare basalts in the Nectaris basin fill only the innermost basin, and mare basalts in the Smythii basin occupy a small portion of the basin floor. Sinus Amoris, Mare Spumans, and Mare Undarum are partially filled troughs concentric to large circular basins. The Tranquillitatis and Fecunditatis are composite depressions containing basalts which flood degraded circular basins and adjacent terrain modified by the formation of nearby cir­ cular basins.

  • Lunar II Logbook
    Astronomical League 1 Introduction and Disclaimer I made this logbook as a convenient place to keep my observations for the Astronomical League's Lunar II Club, and I offer it free of charge to the amateur astronomy community. Please note that although this logbook includes spaces for all of the required observations, it does not include all of the detailed instructions needed to complete the observations. It is intended as a supplement to the official Lunar II observing list, and not a replacement for it. The official observing list can be downloaded freely from the Astronomical League at http://www.astroleague.org/al/obsclubs/lunarII/lunarII1.html . I took the cover image by afocal projection using an Orion XT6 Dobsonian reflector and a Nikon Coolpix 4500 digital camera. It is likely that typos or other errors crept in while I was putting this together. If you find any, please let me know and I will correct them for future versions of this logbook.

Along its northern border is an area called the Palus Somni, while the southern border is an area of irregular terrain that contains the ruined crater Da Vinci. The selenographic coordinates of this bay are 10.8° N, 43.2° E, and it has an overall diameter of 142 km https://en.wikipedia.org/wiki/Taruntius_(crater) Taruntius is a lunar crater on the northwestern edge of Mare Fecunditatis and is named after Lucius Taruntius Firmanus. To the northwest is the lava- flooded crater Lawrence, to the north lie the craters Watts and da Vinci and southwest is the crater Secchi. The outer rim of Taruntius is shallow, but forms a veined, complex rampart in the nearby mare, especially to the north and southwest. The rim is broken in the northwest by the small crater Cameron. The inner rim face lacks terraces, but in the interior is an unusual concentric inner rim that is heavily worn and irregular. This is a floor-fractured crater, possibly created by an uplift of mare material from beneath the interior. There is a low central peak complex in the middle of the relatively flat interior floor. There are also some slender rilles that are concentric to the rim.

  • Javaslat a Planetológiai Nevezéktan Magyar Rendszerére
    HARGITAI HENRIK, KOZMA JUDIT, KERESZTURI ÁKOS, BÉRCZI SZANISZLÓ, DUTKÓ ANDRÁS, ILLÉS ERZSÉBET, KARÁTSON DÁVID, SIK ANDRÁS Javaslat a planetológiai nevezéktan magyar rendszerére Az elmúlt évtizedek során a bolygótani névanyag és szakszókincs egyre szélesebb körben terjedt el: már mindennaposnak számít, hogy akár napi- lapok hasábjain is feltûnnek. A szavak jelentôs részét angolból fordítják. A gyakorlatban az egyes neveket, szakszavakat különféleképpen fordítják – részint hozzá nem értés, részint különféle „iskolák” tudatos névhasználata miatt. Az ûrkutatás gyors fejlôdésével párhuzamosan mind szélesebb körben egyre gyakoribb használatuk várható a jövôben, ezért szükségesnek látjuk a nevek írásmódjának egységesítését, legalább ajánlásszinten. Az alábbi nevek és szakszavak megállapítását többéves elôzetes szakmai konzultáció elôzte meg az ELTE, MÁFI, MTA KTM CSKI, MCSE szakértôi részérôl. Ebben fi- gyelembe vettük a nemzetközi írásmódot és a magyar névhasználat hagyo- mányait is. Ahol nem jutottunk konszenzusra, azt külön jelezzük. Földrajzi nevek A Nemzetközi Csillagászati Unió bolygófelszíni nevekkel foglalkozó mun- kacsoportjának (IAU WGPSN: Working Group for Planetary System Nomencla- ture) alapelve szerint az idegen égitestek helynevei latinos formában írandók. Riccioli 1651-es Hold-térképén még latinul nevezte meg az alakzatokat, mert akkoriban a latin volt a nemzetközi tudomány nyelve. A 19. századra azon- ban már minden nemzet a maga nyelvén nevezte el az alakzatokat, és fordí- totta a hagyományos latin elnevezéseket. Akkor már az egyes szerzôk egyéni neveivel volt tele a Hold térképe. Az IAU 1935-ben tette hivatalossá „letisztí- tott” holdi nevezéktani listáját, még angol formában (például: „Carpathian Mts”). Az 1950-es években a Hold kutatása mind szélesebb közönséget fog- lalkoztatott, így egyre több helyen említették lefordítva a holdi helyneveket. A szovjet felfedezések nyomán születô új neveket az angol sajtó azonnal angol fordításban adta tovább.

  • Hungarian Localization of the International Planetary Nomenclature System
    3rd INTERNATIONAL CONFERENCE ON CARTOGRAPHY AND GIS 15-20 June, 2010, Nessebar, Bulgaria HUNGARIAN LOCALIZATION OF THE INTERNATIONAL PLANETARY NOMENCLATURE SYSTEM Henrik Hargitai Author: Henrik Hargitai Eötvös Loránd University, Institute of Geography and Earth Sciences, Planetary Science Research Group 1117 Budapest, Pázmány P st 1/1 hhargitai[at]gmail.com Abstract: The paper describes the Hungarian localization of the official IAU nomenclature system of planetary body surface features and planetary body names. The localized forms are recommended for use in texts published in popular science journals and newspapers and books for the general public. Keywords: planetary cartography, Mars, Moon, planetary nomenclature, placenames, toponymy INTRODUCTION The Planetary Nomenclature System is maintained by the Working Group for Planetary System Nomenclature (WGPSN) of the International Astronomical Union, and is published as the Gazetteer of Planetary Nomenclature which is distributed by the U.S. Geological Survey (USGS). Planetary surface feature Place Names consist of two elements: a specific term and a descriptor term. Crater, bright albedo and some other names have no descriptor term. Descriptor terms are in Latin language; for specifics, the original form is retained if the original is using Latin alphabet; if not, a transformation to Latin alphabet is applied. The origin of this system goes back to the 17th century, when the first Lunar maps, especially the Grimaldi-Riccioli map used Latin terms which was a conventional custom of cartographers

Section 20 - Lunar Day 15 Tonight we'll begin a limb-to-limb lunar history adventure by learning about the Soviet probe, Lunik 9. In 1966, the unmanned lunar traveler became the first to achieve a soft landing on the Moon’s surface and successfully transmit photographs back to Earth. The lander weighed in at 99 kg, and had four outward opening antenna petals. Within five minutes of touchdown on January 31, the antennae sprang to life and the on-board television cameras began broadcasting the first panoramic images of the surface of another world – thus proving a lander would not simply sink into the lunar dust. Last contact with the spacecraft occurred just before midnight on February 6, 1966. If you'd like to see where Lunik 9’s remains stand, turn your binoculars or telescopes towards the western lunar limb for Oceanus Procellarum. On its western edge, you can easily identify the dark oval of crater Grimaldi. About one Grimaldi- length northward and on the western shore of Procellarum is where you will find Lunik 9’s resting place. Figure 20-1: The major features of the eastern part of the Moon on Day 15 Around the Moon in 28 Days: Lunar Observing for Beginners Figure 20-2: Image from the Luna 9 lander in February, 1966 in the Oceanus Procellarum Now let's go for the opposite limb to check out the eastern edge of Mare Crisium in a different relief.
