Description and Technical Details . In 1980s two medium-size horizontal solar telescopes 50/35000 cm with large spectrographs Czerny-Turner made by Carl Zeiss Jena were installed in the Ondњejov observatory. The Czerny-Turner-spectrographs in the Ondњejov observatory called HSFA1 and HSFA2 according to the German name Horizontal-Sonnen-Forschungs-Anlage ("horizontal device for solar research") have been explored for more than two decades. ...

... Einstein data for SNR are available as images on magnetic tape or diskette and as tables of counting rates. ... In seven cases, with coverage from 35% to 90%, we have calculated an HRI rate for the entire SNR by using the observed IPC data and assuming the ratio of HRI to IPC rates was the same for the observed and the unobserved parts of the remnant. ... Positions of the bright bulge sources and remnants in the galactic plane are known and the rates in table 2 are free of the effects of these. ...

Here is an image a supernova in UGC3683. 11.4.1998. 0.08 UT, CCD ST-7, 520s. Track and Accumulate exposure (13x40s), no filter, dark and flat corrected, temp -20c, telescope used 152/2063 refractor. The image have been taken at the center of our city, Jyvaskyla. The weather was horrible (a full moon was shining and there was clouds on the sky during exposure), so I had stopped imaging in that night. ... Iґll wait for a next clear night and send a better image then. ...

. We give a review of some expander constructions using error-correcting codes and group algebras. We show that applying these constructions to properly choosed codes on modular curves one obtains some new intersting expander graphs. Go to the Laboratoire Poncelet home page.
