The results of a search for ultrarapid variability of galactic water maser sources at the wavelength 1.35 cm on a timescale of several minutes to 1 h are reported. A special observational technique was developed. ... Among those, several sources that have shown such variability were found. ... Clear evidence for such a variability type was found in at least two sources: W49N and W33B. Variability of this kind displays itself only in certain states of the water masers. ...

In particular, it was shown that a considerable fraction (ab. 35%) of the mainbelt M-type asteroids have absorption bands at 3 µm [3, 6] diagnostic of water of hydration. At the same time it was found that the visible-range reflectance spectra of some M- and Sasteroids include absorption features characterizing presence of oxidized silicates [4, 5]. ...

... Piotrovich Main Astronomical Observatory, Pulkovo, St. Petersburg, Russia Received May 24, 2006; in final form, July 7, 2006 Abstract--We have used two astrometric methods developed at the Main Astronomical Observatory of the Russian Academy of Sciences--the method of apparent-motion parameters (AMP) and a direct geometrical method (DGM)--to derive the orbit of the star S2 around the Galactic center, and thereby the mass of the supermassive black hole at the Galactic center. ...
