We report the results of our search for pulsating subdwarf B stars in FullFrame Images, sampled at 30 min cadence and collected during Year 1 of the TESSmission. Year 1 covers most of the southern ecliptic hemisphere. The sample ofobjects we checked for pulsations was selected from a subdwarf B stars databaseavailable to public. Only two positive detections have been achieved, however,as a by-product of our search we found 1807 variable objects, most of them notclassified, hence their specific variability class cannot be confirmed at thisstage. Our preliminary discoveries include: two new subdwarf B (sdB) pulsators,26 variables with known sdB spectra, 83 non-classified pulsating stars, 83eclipsing binaries (detached and semi-detached), a mix of 1535 pulsators andnon-eclipsing binaries, two novae, and 77 variables with known (non-sdB)spectral classification. Among eclipsing binaries we identified two known HWVir systems and four new candidates. The amplitude spectra of the two sdBpulsators are not rich in modes, but we derive estimates of the modal degreefor one of them. In addition, we selected five sdBV candidates for modeidentification among 83 pulsators and describe our results based on thispreliminary analysis. Further progress will require spectral classification ofthe newly discovered variable stars, which hopefully include more subdwarf Bstars.
