An extra leap second has to be inserted at the end of 2008, so this is how you should count down on New Year's Eve to celebrate the start of the International Year of Astronomy according to Irish astronomers. The extra second is needed to bring the uniform measure of time used by physicists using atomic clocks back into nearly exact agreement with time as measured by the rotation of the Earth. ... There will be national and international events organized throughout the year to mark the occasion. ...

... After the best fit is obtained, the confidence limits on two parameters can be obtained by running search_grid . This task calculates a grid of values for a given input model. ... Then search_grid will select the last dataset used (from pkgpars ), will use the best fit from the last run of fit (the null string ``'' at the model prompt will always select the best fit from the _prd.tab file), and will place the results in a _grd.tab file with the same root as the observed file. ...

... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

... Operations of the Hubble Space Telescope (HST) require the creation of stable and efficient observation schedules in an environment where inputs to the plan can change daily. ... A process and software architecture is presented which achieves stable and efficient observation schedules by dividing the task into long term and short term components. ... However, the resulting long range plan would be unstable as unscheduled observations in a week bin would have to be rescheduled. ...
