摘要
The preliminary results of new photometric observations of the delta Scuti stars 7 Aql and 8 Aql are reported. 51 hr of uvby - beta photoelectric photometric data were obtained over the period June and July 2007 at the San Pedro Martir Observatory, Mexico. Period analyses confirm the three pulsation modes discovered in 8 Aql in the framework of the STEPHI 2003 multisite campaign. For the star 7 Aql we were able to detect only the main pulsation modes. The standard magnitudes of both stars are obtained. The frequency, amplitude and phases of the frequency modes in different filters are presented.
