Prognoz-7 satellites magnetometer observation database . The Prognoz-7 satellite was launched 30 October 1978 into orbit with perigee 500 and apogee 203000 km, orbital period was 98 hours. Magnetic field measurements were conducted by SG-70 magnetometer with working range +/- 60 nT., accuracy about 0.3 nT. and sampling rate 1 measurement per 10.24 sec. Magnetic measurements and satellite position data in GSE coordinate system are presented in separate ASCII files. ...

GENERAL DESCRIPTION OF DATABASE . It is a matter of common knoledge, that solar magnetic fields and, in particular, magnetic fields of sunspots, play important role in many solar events. In Pulkovo observatory the long-term data set of daily observations of magnetic fields of solar sunspots was accumulated, which contains great potential for further researches in solar physics. ... Second section includes files containing sum data about magnetic fields for every observational day. ...

... Up: Archives and Information Services . Previous: Search and Retrieval of the AXAF Data Archive on the Web using Java . ... Our Web interface to the HST archive (WDB) was substantially augmented during the past few months: A seamless integration of Java applets and CGI interfaces to the database now allows basic manipulation and visualization of data. ... These applets only require a common Web browser and offer very helpful features to facilitate archive data selection. ...

System of astrometric databases of Pulkovo observatory. ... Pulkovo database of observations of visual double stars . ... The 3rd database contains relative positions of selected double and multiple stars, and stars with possible invisible satellites. The database requires catalog of relative positions of visual double stars, based on photographic observations performed since 1960 on Pulkovo 26-inch refractor, and similar catalog based on CCD observations, obtained since 1995. ...

Wavelengths are based on experimental level energies where available; wavelengths calculated from theoretical energies are less accurate and are given as negative values. ...

While engaged in the forenoon of Thursday, September 1, in taking my customary observation of the forms and positions of the solar spots, an appearance was witnessed which I believe to be exceedingly rare. The image of the sun's disk was, as usual with me, projected on to a plate of glass coated with distemper of a pale straw color, and at a distance and under a power which presented a picture of about 11 inches diameter. ...

Using the GSSS catalog coordinates for the guide stars and the PASS coordinates for the target stars, it was expected that the stars would fall about 1'' from the reference position in the image. ... The analysis clearly demonstrated that the limiting factor in determining the aper­ Figure 2: This plot shows the positions of the stars relative to the reference point as determined from the PASS coordinates and from the images. ture center is now inaccuracy in the catalog coordinates. ...
