... The hot component shows very spectacular activity: irregular outbursts accompanied by fast, massive outflows and jets. ... Diffraction-limited images for both components of CH Cyg binary system were reconstructed using visible speckle interferometry at BTA 6-m telescope (Fig.1). The orbital period 15.6 years and masses: 2.0 Msun and 0.7 Msun for red giant and white dwarf, respectively were derived from angular distance (0.042") and magnitude difference (2 m ) of the components. ...

This is a copy of a Press Release from E.S.O. The most recent ESO observations of bright Comet Hyakutake have shown rapid changes in the innermost coma, within a few hundred kilometres from the cometary nucleus. This result has only become possible because of the unusual combination of a bright comet being near the Earth, together with the excellent imaging quality of the ESO 3.5-metre New Technology Telescope (NTT). ...

We present model fits to spectral energy distributions in the optical and NIR of >100 flat-spectrum radio quasars from the Parkes Half-Jansky Flat-spectrum Sample. We find that ~40% of the sources have power-law SEDs, while a similar number show evidence for two primary components: a blue power law and optical synchrotron emission. ... The sources with power law SEDs show evidence for an excess number of red power law slopes compared to optically-selected quasars. ...

New England observer Lew Gramer, fresh back from his mid-November fish observing and meteor-catching expedition in South Florida, reports that December also promises to be a great month for celestial sky-sparks!" ... Other showers adding to the mix this month include several very minor showers, such as the Chi Orionids (3 Dec), Monocerotids (9 Dec) and Sigma Hydrids (12 Dec), which usually contribute no more than 2 or 3 meteors per hour during even post-midnight observing this month. ...
