Biographical / Historical Russell Tracy Crawford was an astronomer and professor who was associated with the University of California for over 50 years. Earning his degrees in astronomy in 1897 and 1901, he then worked as a professor and astronomer for the university in various capacities until his retirement in 1946. Crawford earned one of the first fellowships granted by the Lick Observatory in 1897, and finished his doctoral work there using the meridian circle with astronomer R.H. Tucker. Crawford is well known for his work in theoretical astronomy, and his observations and computations of comet orbits. He published over a hundred articles and a book entitled The Determination of Orbits of Comets and Asteroids. Crawford was born on March 26, 1876, in Davis, California. -

BV RI Photometry of Supernovae

G. Ho1;2, Schuyler D. Van Dyk3,ChienY.Peng4, Alexei V. Filippenko5, Douglas C. Leonard6, Thomas Matheson7, Richard R. Treffers8 Department of Astronomy, University of California, Berkeley, CA 94720-3411 and Michael W. Richmond9 Department of Physics, Rochester Institute of Technology, Rochester, NY 14623-5603 ABSTRACT We present optical photometry of one Type IIn supernova (1994Y) and nine Type Ia super- novae (1993Y, 1993Z, 1993ae, 1994B, 1994C, 1994M, 1994Q, 1994ae, and 1995D). SN 1993Y and SN 1993Z appear to be normal SN Ia events with similar rates of decline, but we do not have data near maximum brightness. The colors of SN 1994C suggest that it suffers from significant reddening or is intrinsically red. The light curves of SN 1994Y are complicated; they show a slow rise and gradual decline near maximum brightness in VRI and numerous changes in the decline rates at later times. SN 1994Y also demonstrates color evolution similar to that of the SN IIn 1988Z, but it is slightly more luminous and declines more rapidly than SN 1988Z. The be- havior of SN 1994Y indicates a small ejecta mass and a gradual strengthening of the Hα emission relative to the continuum. Subject headings: supernovae: general – supernovae: individual (1993Y, 1993Z, 1993ae, 1994B, 1994C, 1994M, 1994Q, 1994Y, 1994ae, 1995D) 1Also associated with Space Sciences Laboratory, and Department of Physics, University of California, Berkeley. -
Looking for Life at Leuschner
LAMORINDA WEEKLY | Looking for Life at Leuschner Published July 29th, 2015 Looking for Life at Leuschner By Cathy Dausman Many Moraga residents can easily point out the Saint Mary's College hillside observatory. But like a distant star nearly invisible to the naked eye, another observatory sits largely unnoticed among the hills of Lafayette - the Leuschner Observatory that belongs to UC Berkeley. The Leuschner site, adjacent to Briones Regional Park and East Bay Municipal Utility District watershed land, is comprised of two domed buildings. The first holds a 30-inch optical telescope used by astronomy students from UC Berkeley and San Francisco State University. The smaller domed building housing a 20-inch telescope is currently off limits to human occupancy because of its rodent population. "We haven't been in there for decades," said UC Berkeley Astronomy Department Chair Imke de Pater. As rough around the edges as it presently is, Leuschner is still a far sight better than what Cal astronomy students used to rely on. In 1936, the only practical student lab was a small dome atop UC's Campbell Hall. But Campbell Hall's "students' observatory," as it was then called, wasn't cutting it - there was simply too much light and radio wave interference in an urban location. In the early 1960s the Russell family deeded a 283-acre parcel of Lafayette land to Berkeley's College of Natural Resources. It was named the Russell Research Station and was to be used for Inside the Leuschner Observatory in wild land and forestry research. Within the acreage Lafayette Photos Cathy Dausman was a 900-plus-foot hilltop above the fog line and away from light pollution - a far better site for an observatory. -

NL#145 March/April
March/April 2009 Issue 145 A Publication for the members of the American Astronomical Society 3 President’s Column John Huchra, [email protected] Council Actions I have just come back from the Long Beach meeting, and all I can say is “wow!” We received many positive comments on both the talks and the high level of activity at the meeting, and the breakout 4 town halls and special sessions were all well attended. Despite restrictions on the use of NASA funds AAS Election for meeting travel we had nearly 2600 attendees. We are also sorry about the cold floor in the big hall, although many joked that this was a good way to keep people awake at 8:30 in the morning. The Results meeting had many high points, including, for me, the announcement of this year’s prize winners and a call for the Milky Way to go on a diet—evidence was presented for a near doubling of its mass, making us a one-to-one analogue of Andromeda. That also means that the two galaxies will crash into each 4 other much sooner than previously expected. There were kickoffs of both the International Year of Pasadena Meeting Astronomy (IYA), complete with a wonderful new movie on the history of the telescope by Interstellar Studios, and the new Astronomy & Astrophysics Decadal Survey, Astro2010 (more on that later). We also had thought provoking sessions on science in Australia and astronomy in China. My personal 6 prediction is that the next decade will be the decade of international collaboration as science, especially astronomy and astrophysics, continues to become more and more collaborative and international in Highlights from nature. -
IVOA Sky Transient Metadata 06/20/2005 08:00 PM
IVOA Sky Transient Metadata 06/20/2005 08:00 PM Sky Event Reporting Metadata (VOEvent) Version 0.94 IVOA WG Internal Draft 2005-06-20 Authors: Rob Seaman, National Optical Astronomy Observatory, USA Roy Williams, California Institute of Technology, USA Alasdair Allan, University of Exeter, UK Scott Barthelmy, NASA Goddard Spaceflight Center, USA Joshua Bloom, University of California, Berkeley, USA Frederic Hessman, University of Gottingen, Germany Szabolcs Marka, Columbia University, USA Arnold Rots, Harvard-Smithsonian Center for Astrophysics, USA Chris Stoughton, Fermi National Accelerator Laboratory, USA Tom Vestrand, Los Alamos National Laboratory, USA Robert White, LANL, USA Przemyslaw Wozniak, LANL, USA Editor: Rob Seaman, [email protected] Abstract VOEvent defines the content and meaning of a standard information packet for representing, transmitting, publishing and archiving the discovery of a transient celestial event, with the implication that timely follow-up is being requested. The objective is to motivate the observation of targets-of-opportunity, to drive robotic telescopes, to trigger archive searches, and to alert the community for whatever purpose. VOEvent is focused on the reporting of photon events, but events mediated by disparate phenomena such as neutrinos, gravitational waves, and solar or atmospheric particle bursts may also be reported. Structured data is used, rather than natural language, so that automated systems can effectively interpret VOEvent packets. Each packet may contain one or more of the "who, what, where, when & how" of a detected event, but in addition, may contain a hypothesis (a "why") regarding the nature of the underlying physical cause of the event. Citations to previous VOEvents may be used to place each event in its correct context. -
