After the 1992 data of CD-24 7599 had been analysed it was clear, that more pulsation modes than detected must be present. Therefore, the star was re-observed by WET in May, 1994. The number of detectable pulsation frequencies of CD-24~7599 has increased to 13. The 3 dominant modes exhibit amplitude variations with a time scale of one month as well as frequency variations.
7 observatories could acquire data:

• 0.75 meter telescope at the South African Astronomical Observatory, South Africa (observers D. A. H. Buckley and D. O'Donoghue)
• 0.6 meter telescope at Siding Spring Observatory, Australia (S.J. Kleinman and K. Wu)
• 0.6 meter telescope at the Mount John University Observatory, New Zealand (D. J. Sullivan)
• 2.1 meter telescope at McDonald Observatory, Texas (T. K. Watson and M. S. O'Brien)
• 0.6 meter telescope at Mauna Kea Observatory, Hawaii (J. C. Clemens and M. A. Wood)
• 1.6 meter telescope in Itajuba, Brasil (O. Giovannini)
• 1.0 meter telescope at Wise Observatory, Israel (E. Leibowitz)
