Query: Discovery and disentangling of multi-mode delta-Sct pulsations in the
  eclipsing binary V994 Her   Accurate and extensive photoelectric photometry has been obtained of V994 Her
which was discovered as an eclipsing binary by Hipparcos satellite. A marked
pulsation activity is evident in the light-curve, with periods 0.152100488,
0.116836079 and 0.09466580 day that appears to be the contemporanous presence
of fundamental, first and second overtone periods of a multi-mode delta-Sct
pulsation. The latter is observed to remain stable in amplitude and phase over
the whole observaing campaign that lasted between June 10, 2002 and July 15,
2004.
