We present 0.35-2.5 ЮМm spectra of the south and northwest filaments in the reflection nebula NGC 7023. ... Our spectra fail to show their predicted second emission band at 1.0 ЮМm even though both filaments exhibit strong emission in the familiar 0.7 ЮМm ERE band. The northwest filament spectrum does show one, and possibly two, new dust emission features in the near-infrared. We clearly detect a strong emission band at 1.5 ЮМm which we tentatively attribute to ЮВ-FeSi2 grains. ...

... Version 2.0 of the CFITSIO subroutine interface for reading and writing FITS format data files is now available from the HEASARC web site. Some of the major new features in this version are the ability to read FITS files over the network, support for reading IRAF format images, and options for filtering the input file at run time. CFITSIO is a software library that contains both C and Fortran-callable interface routines for reading and writing data files in FITS format. ...

Intensity of atmospheric motions in the mabl retrieved from ocean surface radar imagery M. Mityagina E-mail: mityag@iki.rssi.ru Abstract. The paper is dedicated to the theory and practice of analysis of radar images of sea surface, obtained under unstable atmospheres. In this case, the sea surface reveals wind field variations in the marine atmospheric boundary layer (MABL) caused by atmospheric convec-tive processes, accompanied by air motions with mainly vertical direction. ...
