We report Doppler measurements of α Cen A from time-series spec-troscopy made with UCLES at the 3.9-m AAT. Wavelength calibration using an iodine absorption cell produced high-precision velocity measurements, whose power spectrum shows the clear signature of solar-like oscillations, confirming the detection reported by Bouchy & Carrier (2001). 1. Observations and Reductions We were awarded six ...

We have been using a new method to search for solar-like oscillations that involves measuring temperature changes via their effect on the equivalent widths of the Balmer hydrogen lines. We observed α Cen A over six nights in 1995 with the 3.9-metre Anglo-Australian Telescope and the Eu-ropean Southern Observatory's 3.6-metre telescope in Chile. Oscillations were not detected, with an upper limi...

B, V and R optical photometry performed on the field of the GRB 970111 soon after its detection by BeppoSAX is presented. No remarkable optical object is found inside the corrected error box. The optical counterpart of an X–ray and radio source and a suspected red variable (probably an eclipsing binary) have been detected inside the field of GRB 970111.
