The measurement is achieved using a novel technique that correlates individual photon hits of events to the known position of the Sun. In an energy window between 0.54 MeV to 0.74 MeV, selected using the dominant scintillation light, we have measured 10887$^{+2386}_{-2103} (\\mathrm{stat.})\\pm 947 (\\mathrm{syst.})$ ($68\\%$ confidence interval) solar neutrinos out of 19904 total events.
