ASCA EAO-6 Results
The Japanese/US X-ray astronomy mission ASCA was launched in 1993.Its advanced detectors continue to provide high resolution spectra ofmany classes of astronomical objects.The long list of ASCA discoveriesinclude the detection of broad, heavily distorted, iron linesfrom some Active Galactic Nuclei. These red-shifted lines providedirect evidence for the presence of massive black holes at thecenters of these galaxies.

SOHO in safe mode
At 17:49 UTC on 21 December, the SOHO Spacecraft went intoEmergencySun Reacquisition (ESR). Following a successful gyro calibrationmanoeuvre,prior to a planned orbit correction and momentum wheel managementactivities,the last of SOHO's gyros (Gyro B) failed to give the expected output.This occurred during transition from normal mode to momentum dumping mode,and resulted in the spacecraft transitioning into ESR-10.

Observing pulsating and exotic stars 24 hours a day - MUSICOS98
The fifth large MUSICOS (Multi-site continuous spectroscopy) campaign has just finished, lasting from 20 November to 14 December 1998. It involved 13 telescopes mostly equipped with cross-dispersedechelle spectrographs in Haute Provence, Pic du Midi, La Palma, SouthAfrica, ESO La Silla, Brazil, Kitt Peak, Xinglong, Mt Stromlo, Catania,Caucasus SAO. The campaign was coordinated daily by B.H. Foing and J. Oliveira (Space Science Department of ESA).Although some sites suffered snow and winds, the overall coverage was successful. S.
