Three Chumash-Style Pictograph Sites in Fernandeño Territory
THREE CHUMASH-STYLE PICTOGRAPH SITES IN FERNANDEÑO TERRITORY ALBERT KNIGHT SANTA BARBARA MUSEUM OF NATURAL HISTORY There are three significant archaeology sites in the eastern Simi Hills that have an elaborate polychrome pictograph component. Numerous additional small loci of rock art and major midden deposits that are rich in artifacts also characterize these three sites. One of these sites, the “Burro Flats” site, has the most colorful, elaborate, and well-preserved pictographs in the region south of the Santa Clara River and west of the Los Angeles Basin and the San Fernando Valley. Almost all other painted rock art in this region consists of red-only paintings. During the pre-contact era, the eastern Simi Hills/west San Fernando Valley area was inhabited by a mix of Eastern Coastal Chumash and Fernandeño. The style of the paintings at the three sites (CA-VEN-1072, VEN-149, and LAN-357) is clearly the same as that found in Chumash territory. If the quantity and the quality of rock art are good indicators, then it is probable that these three sites were some of the most important ceremonial sites for the region. An examination of these sites has the potential to help us better understand this area of cultural interaction. This article discusses the polychrome rock art at the Burro Flats site (VEN-1072), the Lake Manor site (VEN-148/149), and the Chatsworth site (LAN-357). All three of these sites are located in rock shelters in the eastern Simi Hills. The Simi Hills are mostly located in southeast Ventura County, although the eastern end is in Los Angeles County (Figure 1). -

A Needs Analysis Study of Amateur Astronomers for the National Virtual Observatory : Aaron Price1 Lou Cohen1 Janet Mattei1 Nahide Craig2
A Needs Analysis Study of Amateur Astronomers For the National Virtual Observatory : Aaron Price1 Lou Cohen1 Janet Mattei1 Nahide Craig2 1Clinton B. Ford Astronomical Data & Research Center American Association of Variable Star Observers 25 Birch St, Cambridge MA 02138 2Space Sciences Laboratory University of California, Berkeley 7 Gauss Way Berkeley, CA 94720-7450 Abstract Through a combination of qualitative and quantitative processes, a survey was con- ducted of the amateur astronomy community to identify outstanding needs which the National Virtual Observatory (NVO) could fulfill. This is the final report of that project, which was conducted by The American Association of Variable Star Observers (AAVSO) on behalf of the SEGway Project at the Center for Science Educations @ Space Sci- ences Laboratory, UC Berkeley. Background The American Association of Variable Star Observers (AAVSO) has worked on behalf of the SEGway Project at the Center for Science Educations @ Space Sciences Labo- ratory, UC Berkeley, to conduct a needs analysis study of the amateur astronomy com- munity. The goal of the study is to identify outstanding needs in the amateur community which the National Virtual Observatory (NVO) project can fulfill. The AAVSO is a non-profit, independent organization dedicated to the study of vari- able stars. It was founded in 1911 and currently has a database of over 11 million vari- able star observations, the vast majority of which were made by amateur astronomers. The AAVSO has a rich history and extensive experience working with amateur astrono- mers and specifically in fostering amateur-professional collaboration. AAVSO Director Dr. Janet Mattei headed the team assembled by the AAVSO. -

An October 2003 Amateur Observation of HD 209458B
Tsunami 3-2004 A Shadow over Oxie Anders Nyholm A shadow over Oxie – An October 2003 amateur observation of HD 209458b Anders Nyholm Rymdgymnasiet Kiruna, Sweden April 2004 Tsunami 3-2004 A Shadow over Oxie Anders Nyholm Abstract This paper describes a photometry observation by an amateur astronomer of a transit of the extrasolar planet HD 209458b across its star on the 26th of October 2003. A description of the telescope, CCD imager, software and method used is provided. The preparations leading to the transit observation are described, along with a chronology. The results of the observation (in the form of a time-magnitude diagram) is reproduced, investigated and discussed. It is concluded that the HD 209458b transit most probably was observed. A number of less successful attempts at observing HD 209458b transits in August and October 2003 are also described. A general introduction describes the development in astronomy leading to observations of extrasolar planets in general and amateur observations of extrasolar planets in particular.
