... Credit: T. Puckett ( Puckett Observatory ) Explanation: This enhanced composite image detailing structure in the coma and dust tail of Hale-Bopp was recorded May 5 - one day before the comet's passage from north to south across the plane of Earth's orbit . ... The comet's interaction with the changing equatorial solar wind and magnetic field during this crossing is expected to produce distortions and disconnections of Hale-Bopp's ion tail . ...

The init method takes the data to model, as well as an instance of your model class (to use as a model for creating new instances), and a map to know the ordering of the properties to their position (as you want them displayed). ...

... For queued observations, the nightly scheduling will be performed by sta# astronomers using an Operational Toolkit. ... The toolkit will make all observation preparation data available to the oper­ ator, and will allow the definition of queues and timelines of Observation Blocks (OBs). ... The operations team then uses the Operational Toolkit to browse the repos­ itory and build queues, based on object visibility, expected observing conditions, and user­defined scheduling constraints. ...

Searching for an Optimal Strategy to Intensify Observations of the Southern ICRF sources in the framework of the regular IVS observing programs ? ... We found that adding more observations of southern sources to the standard schedule causes a slight degradation of some geodetic products and a slight improvement of others, depending on the number of added southern sources. ... As a consequence, the number of observations of the southern sources is very small. ...

... the data are described accurately enough to allow an unambiguous interpretation of the data, as well as a comprehension of the context in which the data were acquired and/or processed; a single ascii file, named ReadMe , is designed for this role. the data are in a format which allows their usage by tools currently in usage in our discipline -- normally flat ascii files ; other formats can be accepted, but are converted into flat files. ...
