... The large field size of UIT is ideal for studies of globular clusters. ... Very metal poor clusters are conducive for the formation of very hot horizontal branch stars which radiate most of that energy in the UV part of the spectrum. ... M31 is the nearest large spiral galaxy to us. ... These are small dwarf galaxies and NGC 205 is a bit unusual because it still has retained some gas for star formation despite its low mass. M33 is an actively star forming spiral galaxy in the local group. ...

A Search for High-z Water Vapor Masers in Obscured AGNs Smita Mathur 1 , Tapasi Ghosh 2 , and Chris Salter 2 1 Ohio State University.. ... These, \megamaser" sources are mostly associated with Seyfert 2 and LINER galaxies whose active nuclei are hidden by a large column density of optically obscuring, X-ray absorbing gas (e.g. Braatz et al., 1997, ApJS, 110, 321). ... Sources out to even a Gpc will thus have detectable (mJy or greater levels) ux density in their water-maser emission. ...

LARGE-SCALE PHENOMENA AT THE SUN ASSOCIATED . WITH FILAMENT ERUPTIONS OUTSIDE ACTIVE . ... Considering the 12.09.1999 event as an example, we analyze manifestations of large-scale disturbances associated with coronal mass ejections (CMEs) caused by filament eruptions outside of active regions. ... The filament eruption occurred in relatively weak magnetic fields, but it was accompanied by larger-scale phenomena than flare events do. ...

... A further spin off of this project is that more reliable pointing information for all exposures is provided. In 1995 the ST-ECF introduced, along with the CADC, the re-calibration on-the-fly (OTF) of archived HST exposures. ... By correlating the HST Mission Schedule and the time-tagged engineering telemetry data stream downloaded from HST it is possible to reconstruct with great accuracy the pointing sequence of any given scientific observation. ... taken within the same HST visit . ...

... One striking feature is a small source of almost pure H 2 line emission, which is located near one of the compact sources in Orion reported by O'Dell and collaborators (HST-18 = 203-504). ... H-H objects, Proplyds, Orion Bar, H 2 . ... We obtained a series of images across the bright rim of the Orion Bar near the peaks of mm-wave molecular line emission with NICMOS cameras 1-3 (NIC1, NIC2, NIC3) in several filters on 1998 February 18. ... The suggestion of an H-H object does not seem compelling. ...
