Trail encounter . ... Expected meteor rates . ... The Leonids are the debris of Comet 55P/Tempel-Tuttle. ... The Earth's passage right through the centre of trails is associated with the most spectacular meteor displays (studies show that, as well as how close to the centre of the trail you are, the strength of the display also depends on how far along a trail's length you are). ... The encounter with the 1932 trail will lead to enhanced meteor activity: a nice outburst, but below storm level. ...

11. ALFA Motor RFI
... The door of the control box was "open" in one case, and "closed" in the other. For this to be a meaningful test, the ALFA feeds were uncovered (to allow sampling of the possible interference), but the array was deliberately not kept at the focus (to reduce possible confusion from sky contribution as well as the usually expected RFI at L-band). ... The left and bottom panels show average spectrum (black), auto/cross-correlation for pairs at the same frequency (green) and the efficiency (blue). ...

The spot may be entirely visible most of the time (one would observe a prolonged flux minimum low), and then part of it may disappear over the horizon briefly and then return (slow rise and then fall back to constant level). ... With the set of observations taken here, I have information available from several comparison stars and color information. ... The period found must be consistent with the data from any given night....

18. Electromagnetic Waves
Perhaps the greatest theoretical achievement of physics in the 19th century was the discovery of electromagnetic waves. ... It is possible to use this to define a unit of electric charge, as the charge which repels a similar charge at a distance of, say, 1 meter, with a force of unit strength (actual formulas make this precise). ... But "field" originally only meant the force a magnet or an electric charge could expect at a point in space, if it were placed there. ...
