First experience in automatic spectral classification related to the MEGA program
The results of automatic quantitative spectral classification of starsin field No. 10 (alpha-1950 = 1 h 18 m, delta-1950 = + 3 deg 13 min) ofthe MEGA program are presented. Some tentative stellar-statisticalresults are discussed.

Photoelectric H-beta photometry for A and F stars brighter than V = 14 M in four areas in directions towards the South Galactic Pole
Data from photoelectric H-beta observations of 145 mainly A and F starswith V = 14 mag or brighter in four regions totalling 60 sq deg andlocated near galactic latitude b(II) = -60 deg, obtained using atwo-channel H-beta photometer on the 1.5-m Danish reflecting telescopeat ESO on two nights in 1981 and four nights in 1982, are presented intables along with the Stromgren b magnitudes calculated from thewide-channel H-beta counts. These observations are undertaken in theframework of a uvby photometric search for A-F stars of Population IIbrighter than V = 15.5 mag. The mean error per observation is given as +or - 0.020 mag in b and + or - 0.009 mag in H-beta.

Speckle interferometry of HIPPARCOS link stars
Speckle interferometry has been carried out on 39 stars that had beenselected as provisionally suitable for linking Hipparcos positionalmeasurements to an extragalactic reference frame by Space Telescope. TheImperial College, London, speckle interferometer and the autocorrelatoron the Anglo-Australian 3.9-m telescope are used. The result is thatabout 30 percent of the stars selected turned out to be confirmed orsuspected multiple stars in the range 0.03-0.7 arcsec.

Photovisual magnitudes of 418 dwarf M stars and 34 parallax stars.
