PENTICTON SOLAR RADIO FLUX VALUES (from SGD Explanation of Data Reports) Daily Solar Flux Values - Penticton -- Daily measurements of the integrated emission from the solar disc at 2800MHz (10.7cm wavelength) have been made by the National Research Council of Canada since 1947. ... The data are tabulated in two forms: the "observed flux" (S), and the "adjusted flux" (Sa). ... The "observed flux" values are useful in ionospheric physics and other terrestrial consequences of solar activity. ...

... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...

... R-band images obtained at 0.8 arcsec seeing conditions have allowed us to separate foreground star from point-like extragalactic source and estimate their brightness separately. ... To study the nature and properties of the source, we observed it under high spatial resolution. ... CONCLUSION RTT150 optical observations with sub-arcsecond seeing and low resolution spectra confirm the hypothesis of superposition of a radio source onto a `normal' F/G galactic star proposed by [1]. ...
