Variability type: EW/KW
Spectral type: F8Vp+F8Vp

GCVS remarks:
ADS 7494 A (B 12.35m, 6.5", 44deg, 1963). dI = 0.037P; Min II 8.43, dII = 0.028P. Soft X-ray source. LX/Lbol = 1.7*10**(-4). P var. Min I = 2420980.8093 + 0.333638880d*E (JD2416000 - 21000); Min I = 2420980.8093 + 0.333636993d*E (JD2421000 - 33000) [01760]; Min I = 2435918.4169 + 0.33363832d*E (JD2433000 - 41000) [05327]; since JD2441000 - see Table. The light curve shape, including depths of minima, var. A moving wave with Delta(m) = 0.025m y and P ~1100d [10067] was noted. A flare (Delta(m) = 1.5m, lambda 3300 A, delta(lambda) = 50 A, JD2438511.7, delta(t) = 7 min) was announced [05788]. The system contains gaseous streams, dark spots on the surface of the components. H and K CaII emission.
