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. ...

Observing with ESO Telescopes . ... ESO-MIDAS . ... ESO Data . ... The pipeline by default interpolates across the bad columns in the REDL CCD when it creates the master bias, but does not so when it processes the science data. This inconsistency can create boxy emission-like features as seen in the figure below. ...

... These are ``quirks'' rather than ``bugs''. Below is a list of quirks. When loading a file and ``Reset Intensity Upon File Load'' is disabled, the intensity range of the previous image will be used. ... When moving between two images (such as when blinking, or when loading a new image), the display system attempts to retain the old image parameters (i.e. zoom box). What is retained are the corners of the zoom box measured in image pixel co-ordinates, not world co-ordinates. ...

... 2006 March 6 . Unexpected Comet Pojmanski Now Visible . ... Explanation: Have you ever seen a comet? ... Comet Pojmanski , officially designated C/2006 A1 and discovered only in January, now sports a turquoise tail several times longer than the full moon. Comet Pojmanski 's ion tail is due to gas particles expelled by the comet being pushed away from the Sun by the solar wind , the same wind that ionizes gas in the tail causing its blue tint. ...

To check this option one needs a detailed map of the NGC 4244 velocity field including HS 1214+3801. ...

... HSP photometric accuracies are strongly dependent on the observational setup and observing conditions, such as spacecraft jitter.
