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. ...

Small Galaxy Groups ASP Conference Series, Vol. ... It is generally accepted that they are related to the nuclear rings formed in barred galaxies at the inner Linblad resonance (ILR), although according to Buta and Crocker (1993), in some cases they were found in non-barred spirals, so in general a presence of large-scale non-axisymmetric gravitational potential is not a rigid condition for the nuclear bar to be formed. Typical length of nuclear bars is 1 - 2 kpc for H 0 = 75km=s=Mpc. ...

Polycyclic aromatic hydrocarbons in HII regions: correlation with metallicity . ... We have perfomed the aperture photometry of HII regions using infrared images from telescopes Spitzer and Herschel at passbands 3.6, 4.5, 5.8, 8.0, 24, 70 and 160 m. Emission of PAHs are observed at passbands 3.6 - 8.0 m, 24 m is emission likely of hot small particles and finally large particles are responsible for emission at 70 and 160 m. We determine abundances of PAHs using model of Draine Li (2007) . ...
