Query: Peculiar seasonal effects in the neutrino day-night asymmetry   We analyze peculiar effects in the day-night asymmetry of solar neutrinos
taking place due to their continuous observation during the night and/or the
year. Namely, we show that the day-night effect contains both a trivial,
cumulative contribution from the whole observation term and a number of
localized terms originating from around the midnights (during the nights) and
the two solstices (during the year). We estimate the latter contributions using
asymptotical methods and discuss the prospects of their isolation, i.e.,
magnification, by contraction of the neutrino observation term to small
neighborhoods of the localization points. In order to complement our
asymptotical predictions derived analytically, we also perform a full numerical
analysis of a temporally-weighted observation of the day-night effect,
including the energy spectrum of the day-night asymmetry and an estimation of
the recoil energy distributions for the elastic-scattering detection channel.
According to both analytical and numerical results, it turns out that a
weighted observation is able to magnify the amplitude of the peculiar
contribution to the day-night asymmetry even to as much as several times the
cumulative term, and it looks feasible and appealing to perform such a
weighting procedure at next-generation detectors to revive otherwise hidden
signatures of the neutrino regeneration effect in the Earth.
