Comet 17P/Holmes increased in brightness over a half of million times on 2007 October 24 ( APOD 2007 October 26 ). On November 1 it was still in peak of its brightness, when I pointed at it the 25-cm telescope of my home observatory located in the Nizhnyj Arkhys, Community of the Special Astrophysical Observatory in Karachai-Cherkesia, Russia. Figure 1. Comet 17P/Holmes identified in the frame of SAO 1-m Zeiss all-sky TV camera on 2007 November 1. ... Comet is a green nonstellar object. ...

... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...
