Parking

 
On street should be available since there are no classes. Copley faculty/staff lot usually not enforced on weekends, but there are only a few spaces. There are some designated visitor spaces on Caroline, across from Fox Hall (just west of Copley), same story on faculty/staff spaces. There is a lot behind Blackwell Auditorium, entrance from Henry Street, driveway next to Duncan Memorial UMC.

 

The Richmond Astronomical Society (RAS) is hosting this years’s VAAS convention.

We’re based in Richmond, VA, about 10 miles south of Ashland.

We meet on the 2nd Tuesday of every month at the Science Museum of Virginia (SMV).

The Virginia Association of Astronomical Societies (VAAS) meets each year as a forum for cooperation and collaboration between the clubs of the Commonwealth of Virginia. Through annual meetings, attendees come away with new friendships, fresh ideas, and knowledge of what other societies are doing around the state and beyond.

The convention started in 1975, and has met continuously (almost) every year since then. There are six ‘core’ clubs that rotate hosting the event. Here’s the list going forward:

2018
Richmond (RAS)

2019

Dr. Michael Skrutskie

Professor and Chair, Department of Astronomy, University of Virginia

I direct a laboratory for the construction of cryogenic near-infrared detection systems. Instruments developed in recent years include the 256 × 256 element NICMOS3 HgCdTe camera (NICMASS), the 2MASS cameras, the CorMASS near-infrared spectrograph, the R=3000 TripleSpecspectrograph which is a facility instrument at Apache Point Observatory and the APOGEE . One of the 2MASS cameras remains active at the PAIRITEL automated infrared telescope facility at Mt. Hopkins, Arizona providing observers in the department quick access to automated observations of the near-infrared sky. The other 2MASS camera operates at the Kuiper 61″ Telescope at Mt. Bigelow, Az, also available to department members through our allocation of time at Steward Observatory facilities. Beyond facilitating my research interests, this laboratory is intended to provide graduate students and undergraduates with hands-on experience with astronomical instrumentation. Current lab efforts include the operation and scientific use of Fan Mountain Infrared Camera operating at UVa’s 31-inch telescope at Fan Mountain Observatory. This camera was designed, constructed and commissioned by students in the department. The laboratory has recently completed a mid-infrared (3-5um) imaging channel, LMIRcam, to support the University of Arizona’s imaging interferometer at the Large Binocular Telescope. This instrument hold the exciting prospect of delivering 30 millarcsecond spatial resolution in the thermal infrared enabling direct imaging and spectroscopy of warm Jupiter analogs orbiting several AU from nearby stars. In parallel the laboratory has designed, fabricated and commissioned its most ambitious instrument to date – a 300-fiber high-resolution (R=22,000) 1.5-1.7um cryogenic spectrograph that is now conducting the APOGEE survey for the third-generation Sloan Digital Sky Survey (SDSS-III). The spectrograph will measure the elemental abundances in 100,000 Milky Way giant stars providing a window on the assembly history of the Milky Way.

The laboratory also maintains facilities to test and characterize infrared arrays. For the last few years we have pursued an NSF-funded program with Goodrich Corporation – Sensors Unlimited to develop and evaluate extended wavelength (2.3um cutoff) InGaAs arrays capable of matching the performance of HgCdTe arrays in ground-based applications. This work has lead to the production of an extended InGaAs array bonded to a cryogenic “astronomical” multiplexer and has been tested in the CorMASS spectrograph.

Dr. Robin Garrod

Professor of Astronomy and Chemistry, University of Virginia

Astrochemistry concerns the behavior of atoms and molecules in astrophysical environments, which can include star-forming clouds and cores, and circumstellar and interstellar regions. The varied gas-phase chemical compositions of these environments are revealed by radio-telescope observations of molecular spectral-line emission and absorption, primarily in the mm and sub-mm bands. Infrared observations also indicate significant solid-phase abundances of simple hydrides, in the form of ices, which coat the sub-micron sized dust grains that permeate interstellar space. The process of star formation – which involves the heating and UV radiative processing of gas and solid-phase material alike – further encourages the production of complex organic molecules that may contribute to the store of pre-biotic material ultimately available on the surfaces of new planetary bodies.

The Garrod group develops and applies new computational techniques to the study of chemical kinetics in interstellar and star-forming environments. A particular focus of the group is the formation and processing of simple and complex organic molecules on dust-grain surfaces and within astrophysical molecular ices.

New techniques recently developed by the group include a unique, fully three-dimensional, off-lattice kinetic Monte Carlo code that can simulate surface chemistry on dust grains of arbitrary size and shape, over interstellar timescales.

Another major focus of the group is the production of complex organic molecules during the star-formation process. We have developed coupled gas-grain kinetics models and spectral simulation tools to explain our recent new detections of organic molecules, including iso-propyl cyanide (i-C3H7CN), the first branched carbon-chain molecule to be detected in interstellar space.

At an early age Randy developed an interest in science, particularly astronomy and space. He received a small refracting telescope for Christmas in 1965 at age 9. He began to observe regularly and record detailed observations in 1971. Although, he was interested in all celestial objects, the planet Jupiter and the Sun were his favorites.

Randy was one of the first observers to see the triple SEB disturbance on Jupiter in 1975. The great upheavals of the SEB, NTrZ as well as the fading of the Great Red Spot were fascinating to see. At that time there were few spacecraft, and no global network of imagers to capture events on the Sun and planets. During the 1976 Jupiter apparition, more than 1100 transit timings of features were made. After reading the landmark paper on the Maunder Minimum by John Eddy in 1976, Randy began to observe the Sun on a regular basis.

Desiring a high resolution planetary telescope; Randy made a 10”f/12 Newtonian refl. in 1981 with the assistance of RAS member, Jean Prideaux. In 1978, he built a spectrohelioscope and coronagraph to study prominences. In 1980 a sub-Angstrom Hydrogen alpha filter was purchased to be used with the 7”f/15 refractor at Ragland Observatory. The fine telescope, with an objective achromat by W.D Mogey & Sons, is well suited for solar imaging.

After several years of drawing celestial objects, Randy began to experiment with astrophotography. Over the years, he progressed to film, videotape and digital webcams. One of his interests was solar active region morphology and solar flare prediction. He has traveled to observe four total solar eclipses and both Venus transits.

Randy has been a member of the Richmond Astronomical society since 1974. For many years he was Observatory Director. He began contributing observations to the Association of Lunar and Planetary Observers in 1974 and was an assistant coordinator in the Jupiter and Solar Sections. Randy received the Walter Haas Award in 2016. His images are shared with other astroimagers and researchers from around the world in the Japan ALPO galleries. Now, after observing the Sun for five sunspot cycles during the “modern maximum of sunspots” it is time to reflect on what has been learned. We may be entering a period of much lower sunspot cycles.

Randy’s interests also include meteoritics, impact crater geology, and archeoastronomy.

He works as a Medical Laboratory Technician.
