... A comparison of the positions of the new HSS ELGs in these diagrams shows that our classification appears to be self-consistent for all BCGs, and, therefore, is rather reliable. It is interesting to compare the positions in diagnostic diagram of the new HSS BCGs with those of the well studied BCGs from the SBS sample (Izotov et al. [ 1994 ], [ 1997b ]; Thuan et al. ... Most of the SBS BCGs populate the region with [N II ] ?/ ... We discover two new HSS BCGs located in this region. ...

Atmospheric Discharge in the Tunguska Disaster . ... Based on the fact that an explosion of the Tinguska cosmic body, which caused trees to fall over a wide area, and radiant energy release during the Tunguska disaster were separated in space and in time, it is proposed that these events are interrelated but of different origin. We propose that the emission during the Tunguska disaster was caused by an atmospheric discharge at altitudes of 10-90 km above the Earth's surface. ...
