Merged catalogue of reflection nebulae Several catalogues of reflection nebulae are merged to create a uniformcatalogue of 913 objects. It contains revised coordinates,cross-identifications of nebulae and stars, as well as identificationswith IRAS point sources.The catalogue is only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/399/141
H2O masers near OB associations Four new water masers have been found in the vicinity of three OBassociations. One of these, in Cep OB3, is among the most intensesources yet discovered and may be related to the most recent epoch ofstar formation in the OB association. Two others, one in CMa OB1, theother in M16, have large radial velocities relative to their associatedmolecular clouds. These results are discussed in the context of starformation and CO line self-reversal within the individual sources.
