In summary, since FOS exposures are not interruptible, a single exposure logsheet line or RPS2 exposure line may produce several distinct FOS exposures and hence several sets of data files. ...

... X-Ray Binaries I . ... In late January 2000 Cygnus X-3 made a transition from a quiescent radio state (low X-ray state) to a radio flaring state (high X-ray state). ... Throughout this activity an extensive multiwavelength campaign was undertaken. These included observations in the hard X-ray (CGRO/BATSE), X-ray (RXTE/ASM/PCA/HEXTE), radio (GBI, Ryle Telescope, VLA, RATAN-600), radio imaging (VLBA), and high resolution X-ray spectroscopy and imaging (Chandra). ...

... The earliest X--ray observations were carried out in the mid--1970s. X--ray luminosities of order L erg/sec were detected in the 2-11 keV range in the direction of the Orion star forming region. ... These observations showed that the O and B stars were the brightest X--ray sources, and that TTs were also associated with emission. Feigelson and Kriss (1981) showed that some of the X--ray sources were associated with PMS stars which had not been previously detected which H surveys. ...

... Precisely one month ago, on 11 July 2009, the last active area of the new solar cycle disappeared from the surface of the Sun. Over the 30 days following this, neither observers on Earth nor devices in space have been able to detect the emergence of any sunspots. ... Therefore, it seems that our star has once again returned to a state of deep solar "winter", following several sparks of activity in May-June 2009. ... To date, this period has lasted 30 days. ...
