Spitzer Infrared Spectrograph Spectroscopy of the Prototypical Starburst Galaxy NGC 7714
We present observations of the starburst galaxy NGC 7714 with theInfrared Spectrograph on board the Spitzer Space Telescope. The spectrayield a wealth of ionic and molecular features that allow a detailedcharacterization of its properties. NGC 7714 has an H II region-likespectrum with strong polycyclic aromatic hydrocarbon emission features.We find no evidence for an obscured active galactic nucleus, and with[NeIII]/[NeII]~0.73, NGC 7714 lies near the upper end ofnormal-metallicity starburst galaxies. With very little silicateabsorption and a temperature of the hottest dust component of 340 K, NGC7714 is the perfect template for a young, unobscured starburst.

Photoelectric measurements of lunar occultations. VIII
Photoelectric timings are reported for 276 lunar occultation eventswhich were observed between March 1975 and February 1976. The timings(in UTC) are based on Loran G equipment of a lunar laser-ranging groupor on WWV signals. Angular diameters are determined for HR 5301, HD176124, Chi-1-Orionis, and HR 601. Twenty cases of possible or actualdouble stars, including Beta Capricorni, are noted along with oneprobable triple system (51 Piscium). Several technical and computationaldifficulties encountered in this program are discussed.
