Helioseismology requires nearly continuous observations of the oscillations of the solar surface for long periods of time in order to obtain precise measurements of the sun's normal modes of oscillation. The GONG project acquires velocity images from a network of six identical instruments distributed around the world. The GONG network began full

We report on narrow-band Hα imaging and long-slit spectroscopy at intermediate resolution from [NeV] lambda3425A to [SIII] lambda9532A at PA=25.˚5 through the nucleus of the Seyfert 2 galaxy NGC 5347. The nucleus shows very-high-excitation lines, such as [NeV], HeII, [FeVII] and [FeX]. At 3 arcsec to the north-east there is a high-excitation

In this paper we present the BV-CCD photometry of three stellar fields of the Large Magellanic Cloud (LMC). They are taken at the center of V-charts of the Hodge & Wright (1967) catalog after which they are named. The fields under examination are LMC-30 (2degNorth-West of the Bar), LMC-45 ( 2degNorth of the Bar) and LMC-61 ( 3degNorth-East of the

We present mid-resolution spectroscopic observations of 63 faint (V=12-16) stars identified by Kun (1992) as Hα emission candidates in an objective prism survey of several high galactic latitude molecular clouds. Only 4 stars in our sample (6%) are bona fide T Tauri stars on the basis of their strong Li I absorption and Hα emission features. They

We analyze time sequences of photospheric spectral lines in the penumbra of two sunspots. Two spectral lines sensitive to velocity fluctuations at two different heights in the atmosphere (Ti I 8396.9A and Fe II 7224.5A) are used. The observations were taken using the Gregory-Coude Telescope (GCT) at the Observatorio del Teide (Tenerife). Velocity

Measurements on the local seeing have been carried out during two and a half yea rs (March 29, 1992 to October 7, 1994), over a total of 378 nights. The Site Tes ting Telescope (STT) from the Steward Observatory yields a median seeing of 0.61 arcsec and a first quartile of 0.50 arcsec. Additional measurements with the Carnegie Monitor (CM), many of
