... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... Auroral Currents . ... 25c. Space tether . ... Aurora from Space . ... But the best view is still from space. ... The Canadian scientific satellite Isis-2 (1971) carried an auroral imaging camera and discovered the diffuse aurora, a broad ribbon around the auroral oval, too spread-out to be noticed from the ground. ... Currently, NASA's Polar (1996) collects images of the polar aurora using three cameras--in visible light (sometimes as frequently as 12 seconds apart), in ultra-violet and in x-rays. ...

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. ...

... 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. ... Fig.1. ...

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

... In the central equatorial Pacific, the large area of warmer than normal sea surface temperatures (large area outlined in red with a white center) associated with growing El Nino conditions has recently migrated eastward toward the coast of South America. http://physicaplus.org.il/zope/home/en/1105389911/1113511992_en На этой странице есть презентации с конференции, где активно обсуждалась . ...

Consequences of Impacts of Cosmic Objects in Circumstances of Changing Climate . ... The consequences of the impacts of asteroids about 1 km in size on the Earth are considered from the viewpoint of their negative effects under conditions when the climate changes. These effects are ejection of greenhouse gases, fires, changes in surface albedo, and global dispersion of asteroid material. ...

One might be tempted to think that the basic task of keeping track of the time would not change that much from one kernel to the next. ... One change which shouldn't be problematic for most code is the change in the internal clock rate on the x86 architecture. In previous kernels, HZ was 100; in 2.6 it has been bumped up to 1000. ...
