... Team . ... GRB mini-workshop 2006 . ... On April 8, 2005, an optical afterglow of the GRB 050408 was discovered with the SAO's telescopes (the 1-meter telescope Zeiss and 6-meter telescope BTA) within the framework of a joint BTA request (SAO RAS + IAA CSIC, Granada, Spain) on optical identification of gamma-ray bursts. We first detected a variable object only by our own data in the localization error-box reported by the space observatory HETE and then it was confirmed by our observations in SAO. ...

... Ignacio Ugarte Urra's PhD thesis topic is the investigation of coronal bright points. In his first paper (in collaboration with Gerry Doyle and Maria Madjarska) he investigated the formation, evolution and decay of a coronal bright point via a spectroscopic analysis of its transition region counterpart and the evolution of the underlying magnetic bipole during 3 days of almost continuous observations. ... In general the bright point has a radiance 4 times higher than that of the network. ...

... A new IRAF task has been developed that automatically identifies linear (line-like) features in an image or set of images. ... In order to automatically detect linear features, the first step is to select pixels in the image (Fig. 1 , left panel) that fall within a given data value range. ... Another aspect of extended linear features is that the image space pixels that describe them are in some way adjacent to one another and have a minimum and maximum length. ...
