An overall view of the solar surface is presented with emphasis on the study of low 1 value oscillations. Line of sight velocity measurements of the whole solar disk were made using optical resonance spectroscopy. Constancy of the peak of spectral emission is demonstrated in two ways; first, the observed peaks in the power spectra are numbered

We report an unusual case of a two-ribbon flare associated with an umbral brightening in a magnetically unipolar region.

A three-dimensional equation for deriving the scattering properties per unit volume of interplanetary space is obtained. The equation is related to the zodiacal light intensity observed from a photometer set in some arbirary position relative to the zodiacal light symmetry plane.

A new technique to perform speckle interferometric measurements at J, H, K, L and M wavelengths is described. The time-averaged spatial frequency power spectrum of an image is obtained by scanning it successively over a series of gratings of differing spacing. Some measurements on a 1.5-m telescope are reported which show that diffraction-limited

JHKLM photometry of Nova Cygni 1978 taken over the period 1978 September 20-26 is presented. Evidence for a strong depression in the L band is noted. There is no evidence for an M band emission peak exceeding about 0.1 mag.
