  We would like to discuss prospects for neutrino observations of the
core-collapse supernova progenitor during neutrino-cooled stage. We will
present new theoretical results on thermal neutrino and antineutrino spectra
produced deep inside the pre-supernova core. Three competing processes: pair-,
photo and plasma-neutrino production, are taken into account. The results will
be used to estimate signal in existing and future neutrino detectors. Chance
for supernova prediction is estimated, with possible aid to core-collapse
neutrino and gravitational wave detectors in the form of early warning.
