1. Rapid Changes in the Inner Coma of Comet Hyakutake
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). ...

3. Initial Hypotheses
... Jitter is usually very small in magnitude and random in effect, and is not expected to lead to systematic throughput changes. ... However, such a change should lead to an obvious decline in the strength of the comparison lines at one end of the spectrum relative to the other and not an overall decline in counts. No such effect is seen (the counts decline evenly from one end of the spectrum to the other). ... The value changes steadily, but not by enough to account for the changes in counts seen. ...

5. Gravitational Lensing by Stars
This animation shows a binary star being lensed by a binary lens. ... The sharp changes in the size of the lensed images of the stars lead to sharp changes in the brightness of the stars, which can be analyzed to determine many parameters about the objects doing the lensing, even though they are not bright enough to be seen. ... The graph shown above gives the predicted and observed brightness of a star in the Small Magellanic Cloud being magnified by a binary lens. ... Tutorial : Part 1 | ...

7. Phil Plait's Bad Astronomy: Misconceptions
... 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. ...

12. Changing transfer authorisation for a host
. You can also use the hhstore command to remove the stored authorisation for a host whenever you change your password. For example: hhstore -r festival . This removes any access authorisation that you might have stored for the host "festival". Use of the -r option indicates that you want to remove the current authorisation for a host.
