In March 1993 a coordinated photometric campaign of FG Vir was undertaken by DSN and WET. Two different observing techniques, three star method and high speed, were adopted in order to optimize the quality of data in different frequency ranges.
8 observatories obtained 170 hours of data :

• 0.75 meter telescope at the South African Astronomical Observatory, South Africa (observer J.E. Solheim)
• 0.8 meter telescope at McDonald Observatory, Texas (G. Handler and E. Serkowitsch)
• 2.1 meter telescope at McDonald Observatory, Texas (T.K. Watson and R.E. Nather)
• 0.6 meter telescope at Xing-Long station of Beijing Observatory, China (Jiang Shi-yang)
• 0.6 meter telescope at Siding Spring Observatory, Australia (S.J. Kleinmann)
• 0.6 meter telescope at Mauna Kea Observatory, Hawaii (M.A. Wood)
• 0.6 and 1.0 meter telescope at the Mount John University Observatory, New Zealand (D. J. Sullivan)
• 1.0 meter telescope at Wise Observatory, Israel (H. Mendelson)
• 0.6 meter telescope at Mt. Suhora, Poland (J. Krzesinski and G. Pajdosz)
