  The recently reported solar neutrino signal in the $^{71}$Ga GALLEX detector
adds a new dimension to the solar neutrino puzzle, complementing the previously
known signals in $^{37}$Cl and water-Cherenkov detectors. Possible explanations
for this new signal in terms of matter-enhanced neutrino oscillations (MSW
effect) are already awaiting in the literature. We point out here that
long-wavelength vacuum oscillations can furnish an alternative explanation of
all three signals simultaneously; such solutions give neutrino spectra with
distinctive energy dependence and seasonal time dependence. %This is a Revtex
