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. ...

ACTIVITY TITLE: Thermal Verification ID: TCS-01 APPLICABLE REQUIREMENTS: L.10.4.13.1 DESCRIPTION: The determination of the impact of NOBL installation is expected to be ongoing for Bays 5, 7 and 8, likely through and past the SMOV period. ... Bays 5 and 8 are expected to have greater impact following successful installation of the NOBL-ER. Since the changes are not expected to have critical impacts, no specific thermal verification is really warranted for the SMOV period. ...

... Actual stars are expected to be more complicated than these simulations. ... 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....

Mal Ruderman (KIPAC, Stanford) . What do we see when we look at the surface of a neutron star from a great distance? ... The new point that is made is a consequence of near-relativistic electron-positron flows expected in the near-magnetosphere's of "young" (not older than about a million years) neutron stars. Because of cyclotron resonance scattering by these pair-flows on surface X-ray and UV emission, we do not see unprocessed suface emission. ...
