In this report, we present the results of a STARE's three month observational
run centred at the Cygnus constellation. STARE uses a 9.9 cm aperture, 286 mm focal
length automatic telescope installed at the Observatorio del Teide (Spain) and funded
by NASA Origins of the Solar Systems programme. A total amount of aprox. 14000 stars with
9<R<12.5 magnitude, in STARE's 6.1x6.1

FOV, has been analyzed to obtain lightcurves
of each of these stars. The data spans for more than 85 nights. In this single field, we detect
more that 40 stars with pulsation modes between 5 and 40 c/d, the vast mayority previously unknown
to be variables. A big number of eclipsing binaries and long period pulsating stars has also been
discovered.
Scuti with clear oscillations in the low frequencies
region, with two peaks in a 2:1 frequencies ratio, that we might interpret as binarity
