Barrow, C. M.; WOliams, J, R. (Florida State Univ., Tallabeecess). Nature (Loudoa), 316; 462-S(Mov. ¢, 1987). It was reported earlier that almost continmous ‘burstyradiatian from Jupiter could be detected st lowfregaencise if an asrialsystem of suff; A increase tn eralesion Probability at 30.3 Mewas also tamd wateg the large array at Clark Lake Radio Observatary. Evidesce presented in this communication of a related effect at 18 Ma a served on several occasions during the 1966-67 apparition of Jupiter; this refers to a r jy ateady 4 appearing as a background to the ‘more sual “bursty” type of emission, The observations were made with an interferometer consisting of two ideatical broadside arrays, each consinting of four whole-wave dipoles, on an E--W bescline of 16 wavelengths. The event characteristics are tabulated. A total of 17 events out of 43 observed during the period November 5, 1966 to March 4, 1967 contained evidence of continuum emission. That this effect waa Bot observed on every occasion presumably indicates thai the conUncum emissice is either not a frequem occurrence at 18 Mo, or that ft te sivays present but emuelty of too low invensity to be recorded (UK aver CASE OF THE VANISHED CORRELATION IN STATISTICS OF QUASI-STELLAR OBJECTS, of Coloredo, Boulder), 1967), Gamow,G, (Univ, Nature (London) 218: 461-2(Nov. 4, The result of the studies by Longair and Scheuer (Nature 215: 919 (1967}} concerning the possible cor. elation between optical and radio intensities and red shifte in quasare are discussed. These authors found that correlation dlasppeared when the effects of rela- tivietic time dilation were eliminaten An exp‘anation of this disappearance is offered, based on absorption by galaxica. The obeerved Doppler effect in the absorption lines will correspond not to the Tecearion velocity of the source, but to that of au iatervening galary.

Except for Tom 356, none of the objects exhibits emission lines. A apectrophotometric study was made of the quasi-stellar galaxy Tom 256, discovered by Sandage. The physical parameters of the gapeous envelope are derived from ths forbiddem-line ineneities. The eimation is found to be similar to the phenomena observed im Seyfert galaxy suclel, but on 8 larger soske. (math) am POSSIBLE POLARIZATION OF BRE MSSTRAMLUNG X RADIATION FROM SOLAR FLARES.
