We report on a sudden brightening of the dwarf nova WZ Sge during decline from outburst (cf. IAUC #7669, IAUC #7670). The observations were made with the 0.82-m IAC80 telescope at Teide Observatory (Tenerife, Spain). The object has risen approximately two magnitudes, and CCD photometry gives B=11.33 +/- 0.01 and R=11.09 +/- 0.01 (August 21.875 UT)

The COMPTEL observations of the diffuse galactic 1.809 MeV emission attributed to the radioactive decay of 26 Al have confirmed the diffuse nature of this interstellar emission line. One of the most significant features of the reconstructed intensity pattern is a flux enhancement in the direction of the Cygnus region. This region is fairly young

We report new (1995) Very Large Array (VLA) observations and (1984-1999) Effelsberg 100 m monitoring observations of the 22 GHz H2O maser spectrum of the Seyfert 2 galaxy NGC 1068. The sensitive VLA observations provide a registration of the 22 GHz continuum emission and the location of the maser spots with an accuracy of ~5 mas. Within the

The description of the PESCA instrument control system is presented. The PESCA instrument has been designed and built with the purpose of studying the Solar Energetic Particles and the Anomalous Cosmic Rays from helium to iron in the energy range 1.5-50 MeV/uma and will be part of the Russian PHOTON satellite payload. The instrument comprises two

The equilibrium configuration of very small magnetic flux tubes in an intergranular environment automatically produces kilogauss magnetic field strengths. We argue that such a process takes place in the Sun and complements the convective collapse (CC), which is traditionally invoked to explain the formation of kilogauss magnetic concentrations in
