... SERENDIP IV, the latest SERENDIP instrument, consists of 40 spectrum analyzer boards working in parallel to look at 168 million narrow (0.6Hz) channels every 1.7 seconds. ... We installed SERENDIP IV at the Arecibo Observatory on June 11, 1997, and have been since receiving raw data from the observatory at the rate of one megabyte every four minutes. ... The SERENDIP I instrument consisted of a 100-channel spectrum analyzer which was located at UC Berkeley's Hat Creek Observatory. ...

Peremennye Zvezdy ( Variable Stars ) 33 , No. ... We present two transiting exoplanet candidates in Cygnus discovered during a small photometric survey performed at the Kourovka Astronomical Observatory of Ural Federal University in the summer of 2012. The MASTER-1 b candidate (host star 2MASS 20260213+5006032, ) has a period of 0 847, transit depth of 0 015, and transit duration of 1 6. ... Observations, data reduction, transit search tools, and detected candidates are described. ...

... The TESIS is a set of solar imaging instruments developed by the Lebedev Physical Institute of the Russian Academy of Science, and launched aboard the Russian spacecraft CORONAS-PHOTON on January 30, 2009. The main goal of the TESIS is to provide complex observations of solar active phenomena from the transition region to the inner and outer solar corona with high spatial, spectral and temporal resolution in the EUV and Soft X-ray spectral bands. ... Solar activity hits a new low . ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...

... VaST is a software tool for finding variable objects on a series of astronomical images. ... VaST performs object detection and aperture photometry using SExtractor on each image, cross-matches lists of detected stars, performs magnitude calibration with respect to the first (reference) image and constructs a lightcurve for each object. ...
