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 the detection at X-rays of the radio/optical jet of 3C 371 from a short (10 ks) Chandra exposure in 2000 March. We also present a new MERLIN observation at 1.4 GHz together with a reanalysis of the archival Hubble Space Telescope Wide Field Planetary Camera 2 F555W image. Despite the limited signal-to-noise ratio of the Chandra data, the

In 1998 the EXPORT team monitored microlensing event light curves using a charge-coupled device (CCD) camera on the IACQ4 0.8-m telescope on Tenerife to evaluate the prospect of using northern telescopes to find microlens anomalies that reveal planets orbiting the lens stars. The high airmass and more limited time available for observations of

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)

Hubble Space Telescope (HST) V- and I-band observations show that the gravitational lens B1359+154 consists of six images of a single zs=3.235 radio source and its star-forming host galaxy, produced by a compact group of galaxies at zl~=1. Very Long Baseline Array (VLBA) observations at 1.7 GHz strongly support this conclusion, showing six compact
