What is recorded here?
The Borexino Collaboration extracted a real-time spectral signal attributed to 0.862 MeV beryllium-7 solar neutrinos from electron recoils in a low-background liquid scintillator. For the first 47.4 live days in 2007 the reported interaction rate was 47 ± 7 statistical ± 12 systematic counts per day per 100 tonnes.

Scientific scope
The experiment measures a recoil-energy distribution rather than a direction or individual neutrino energy. The two spectral analysis methods use the same detector data and are not independent observations; fits depend on radioactive-background shapes and light yield. The early fiducial-mass estimate dominates the stated systematic uncertainty, while krypton background and signal are correlated. CNO and bismuth components could not be separated in this analysis, so the later CNO result is distinct. Prior radiochemical solar-neutrino detection and higher-energy real-time observations retain their credit. The individual contributor list shown here is incomplete. The exact arXiv v1 side date is 16 August 2007, whereas its rendered footer states 6 December 2021; this apparent generated-date inconsistency is not treated as a 2021 observation.
