Peremennye Zvezdy ( Variable Stars ) 32 , No. ... We report on a new episode of decretion disk formation in the IGR J06074+2205 system. ... From a study of three HeI lines, the rotational velocity of the star was determined as km/s. After five years of spectroscopic monitoring of IGR J06074+2205 (Reig et al. 2010), a reversion from emission to absorption of the H line and hence disappearance of the equatorial disk was reported. ...

Brad Carter, Carolyn Brown, Rhodes Hart Drew Foster, John Kielkopf, Ron Moore University of Southern Queensland, Australia University of Louisville, Kentucky, USA OVERVIEW Mt Kent Observatory is now providing live remote observations of southern skies as part of a collaborative project between USQ, the University of Louisville, and Northern Kentucky University. ... This enables observers to make daytime use of a remote telescope during its local night-time, and image otherwise inaccessible skies. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

... Space flight . Crew training . ... The principle of the existing reliability level of space engineering, and first of all, of rocket-launchers is laid into the milestone of the cosmonauts training (the successful launch of "Soyuz" space vehicle is close to 1, but it is less than 1), that causes a possible landing of space crews outside the regular landing site. ... However, search operations can be hampered by difficult meteorological and geographical conditions in the region of emergency landing. ...
