ATMoB "Open Cluster Observing Award " Guidelines Purpose: To promote observing among the membership of the Amateur Telescope Makers of Boston through participation in the Open Clusters Observing Awards program. Introduction: This awards program is oriented towards visually observing open clusters above magnitude 9.9. ... It turns out that a very unprejudiced and convenient method to dermine the limiting magnitude is to count the number of visible stars in certain areas on the sky. ...

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) . ...

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. ...

It is shown that in this very general framework the well established anti-correlation between variability amplitude and wavelength can only be understood as an effect of an underlying spectral component which remains stable on long time-scales, and is redder than the variable component. ...

. 1. Move the cursor to the start of the text block you want to define. 2. Type M-space (the META character followed by a space). This sets a 'mark' at the start of the 'region'. 3. Move the cursor to the end of the text block you want to define as the 'region'. This sets the 'point' at the end of the 'region'. You do not have to type anything to set this 'point', the 'point' is the location of the cursor.

We have taken diffraction-limited ( 0.15") near-infrared F160W (henceforth H-band, for convenience) images with NICMOS on HST of the center of the R136 cluster (age 3.5 Myr) in the core of the 30 Dor giant HII region in the Large Magellanic Cloud. ... 1996, ApJ 466, 274) can sample only M >2M , while previous V and I band HST images with WFPC2 (Hunter et al. ...

... The fact that the Sun is a gas, however, lets different regions pass by one another fluidly. ... This differential rotation has interesting ramifications for the Sun's magnetic field. ... This bizarre distortion of the magnetic field results in active phenomena on the surface of the Sun. ... Magnetic instabilities in the solar field cause short, violent ejections of gas called solar flares-the most explosive events on the Sun. ... The Sun can also be viewed safely through special types of filters. ...

Short-Period Comets: Origin and Terrestrial Impact Hazard . ... The model is consistent with the basic observed distributions of near-parabolic comets, short-period comets, Centaurs and high-eccentricity trans-Neptunian objects.This model requires that initial objects in the early Solar System are concentrated to the outer planetary region, and the physical lifetime of comets in the inner planetary region at the present epoch is an increasing function of initial perihelion distances. ...

... INTRODUCTION There are four co-aligned instruments onboard the INTEGRAL (The International Gamma-Ray Astrophysics Laboratory) satellite: (1) gamma-ray imager IBIS (15 keV­10 MeV, field 9 deg, 12 arc min FWHM), (2) gamma-ray spectrometer SPI (12 keV­8 MeV, field 16 deg), (3) X-ray monitor JEM-X (3­35 keV, field 4.8 deg), and (4) optical monitoring camera OMC (Johnson V-filter, field 5 deg) [1]. ... Most symbiotics are the long-period causins of CVs and X-ray binaries. ... IBIS ­ all obs. ...
