Abstract

We present a brief informative overview of a broad ranges of subjects, the solar, the reactor, the geo and the supernova neutrinos (but without excluding possible biases), the topics which consist of the session “Neutrino Physics around MeV Energies” in NOW2006. Contrary to the naive expectation, the field is found to be very active in improving the performance of existing detectors, and in preparation for the development coming in the near future. The former includes excellent performance of SNO 3He detector, successful reconstruction of SK III, and KamLAND's new “4 π” calibration. The next data release from these experiments will be very exciting. The latter includes effort for lowering threshold in SK III, KamLAND's purification by which geo-neutrino observation becomes much cleaner, and the forthcoming 7Be neutrino measurement by BOREXINO and KamLAND. Possible detection of relic supernova neutrinos and non-zero effect of θ 13 would bring us great excitement. Furthermore, improved new measurement of heavy element abundance in the solar atmosphere resulted in a solar model with much lower CNO ν flux and with disagreement with helioseismology, thereby bringing us a new solar puzzle.
