Observations of Galaxies with the Midcourse Space Experiment
We have imaged eight nearby spiral galaxies with the SPIRIT III infraredtelescope on the Midcourse Space Experiment (MSX) satellite in themid-infrared at 18" resolution at 8.3, 12.1, 14.7, and 21.3 μm. Eachof the eight shows interesting structure not previously detected witholder, lower resolution infrared data sets, such as a resolved nucleusor spiral structure. The MSX data are compared with existing data setsat ultraviolet, optical, and infrared wavelengths, including recentobservations from the Infrared Space Observatory. The infraredstructures in M83 and NGC 5055 show a striking similarity to theultraviolet emission but are less similar to the optical emission.Several point sources with no identified counterparts at otherwavelengths are found near M31, NGC 4945, M83, and M101. Over 200previously known objects are also detected at 8 μm.

The multiple frequencies of the δ Scuti variable CC Andromedae.
By applying a new multiple-frequency analysis to observations of CCAndromedae made by Fitch in 1956 and 1957, a seven-frequency solution,incorporating the six frequencies of Fitch together with a new one of7.9024cycles/day, has been developed. The seven frequencies were used tofit the new photometric data of CC And obtained at Beijing AstronomicalObservatory, as well as nine other data sets and provide more accuratefits to all of the data than the six frequencies do. Based on thecalculation of Q values for the seven frequencies, the pulsation modeidentification of CC And was made and indicates that CC And is apulsator with multiple nonradial pulsation modes and a low rotationalvelocity.
