High-resolution maps of Jupiter at five microns.

The distribution of 5-micron radiation, emitted from a large number of discrete sources from Jupiter, was observed during the 1972 apparition. These sources are less bright than those observed by Westphal (1969). At least 50 discrete sources having brightness temperatures exceeding 227 K were revealed which were mainly located within three narrow-latitude bands. Strong correlation exists between the 5-micron brightness temperatures of Jovian features and their colors as recorded photographically.

The Annual Variation in the Radiant Distribution of Sporadic Meteors

Meteor data obtained from the Southern Hemisphere confirm that the strengths of the helion, apex and antihelion sources of sporadic meteor activity are in the ratio 2 :1 : 2 when averaged over a whole year. During the year the helion and anti-helion source strengths vary from 0.8 to 4.0 times that of the apex.
