Advisor's project abstract: . ... The reduction and analysis of H-alpha and ultraviolet spectra, and comparison to other objects is a good summer project. ... The cryogenic x-ray detector research group is seeking a summer student to assist with the development of a balloon payload for studying the hard x-ray emission and the processes of nucleosynthesis in supernova remnants. ... The full archival project includes 29 galaxies; this pilot project would include 2-4 galaxies. ... Abstract: . ...

... I): We observed spectrophotometric standard white dwarf stars and compared the observed counts with pre- ight values to calculate the correction factors known as 'fudge factors' for each lter. ... A new distortion map for the U- lter has been made by comparing the actual and predicted positions of 813 stars in an OM calibration eld. ... Figure 10: The histogram of dark counts 12 Figure 11: Out-of-focus ghost image ("smoke ring") caused by re ection of bright eld stars during SA95 observation (B lter...

... Events . ... Occultations by Kuiper Belt Objects . ... Thursday, Jun 11, 2009 at 8:00 PM . A stellar occultation occurs when a solar system body passes between a star and an observer. ... The atmospheres of the major planets, three of the four planetary ring systems, and numerous asteroids have been probed with stellar occultations. ... With stellar occultation data we can also probe for close companions and possible tenuous atmospheres. ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

ARCSAT ID NUMBER: AS04 DESCRIPTIVE TITLE: Constraining the magnetic fields of transiting exoplanets through ground-based near-UV observations PI: Jake Turner OBSERVER(S): Jake Turner (Graduate Student: University of Virginia) Apurva Oza (Graduate Student: University of Virginia) Robin Leiter (Undergraduate Student The magnetic field of a transiting exoplanet can be constrained by observing asymmetries in their near-UV light curves (Vidotto, Jardine Helling 2011a; Vidotto et al. ...

... The Palomar Testbed Interferometer (PTI) is a 110-meter baseline K-Band infrared interferometer located at Palomar Mountain, California. In 1999 an effort was started to provide more observer-friendly observation planning and monitoring tools, such as might be used in NASA interferometer missions. This session illustrates how these prototype tools aid in the observation of spectroscopic binary stars. ... In 1999 an effort was undertaken to prototype mission operations support tools at PTI. ...

... Hold on, got to take my anti Malaria pill. ... Oh, and elsewhere in this issue, you'll find a report describing the AAAP picnic. ... AAAP picnic at Rex Parker and his wife residence on June 16th will start at 4:30 pm with observing at the Simpson observatory at twilight. ... Ron Mittlesetadt Observations A.O.S.

. Ross-Nazzal: Today is March 17th, 2005. This oral history with Charlie Walker is being conducted for the Johnson Space Center Oral History Project in Washington, D.C. at NASA Headquarters. Jennifer Ross-Nazzal is the interviewer, assisted by Sandra Johnson. This is Mr. Walker?s second oral history session. Thanks again for joining us this afternoon. Walker: Thank you very much for having me back. Ross-Nazzal: Yes. I always enjoy it. I think it would be prudent for us to actually start with your first
