Astronomers at Armagh Observatory observed the partial eclipse of the Sun on 29 March under unusually good conditions. ... The images, taken by astronomer Miruna Popescu, shows the eclipse as seen from the Armagh Observatory at around 11:30 (Summer Time) on 29th March, and the way it was observed by astronomer Apostolos Christou with a small portable telescope equipped with a filter to protect against the Sun's dangerous radiation. ...

Compilation of cz (radial velocity) measurements . HyperLeda home | Documentation | ... The catalog (table a110 in the database) presents the compilation of redshift of galaxies, z , z = ( - 0 ) / 0 = ( 0 - ) / where and 0 refer the observed and emitted wavelength, and 0 are the observed and emitted frequency. ... For homogeneity of the HyperLEDA, the radial velocity from "radio" convention has to be transferred to redshift using formula cz = V radio / (1 - V radio /c). ... radio measurement . ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...

... Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ...

However, molecular emission features are only very rarely observed in the optical spectra of PPNe. ... On the other hand, it is well known that cometary nuclei spectra show prominent Swan band emission. In both spectra of IRAS04296 we have discovered strong emission in the (0;0) and (0;1) bands of the Swan system of the molecule. ... Now consider the case of IRAS04296. ...
