Maintained by D. A. Green at the Cavendish Laboratory in Cambridge, this is a comprehensive scientific catalogue of 310 known Galactic supernova remnants, updated through October 2024. It includes detailed listings, alternate names, summary data, and links to astrophysics literature via the ADS system, making it an essential reference for researchers and astronomy enthusiasts alike.
http://uksmg.org/content/deadband.htm
Written by Palle Preben-Hansen (OZ1RH), this technical article explains how radio amateurs can make long-distance contacts on the 50MHz (Six Meter) band by exploiting meteor scatter propagation even when the band appears dead. It covers meteor trail geometry, shower timing, diurnal and seasonal meteor rate variations, and practical operating techniques, with supporting figures and links to software and IARU procedures.
