GALLEX solar neutrino results and status of GNO

We describe the results of the GALLEX solar neutrino experiment after completion of the project. In particular, we summarize the results for GALLEX IV (12 solar runs) and for our As-71 - spiking experiments. The integral GALLEX result for all 65 solar runs (GALLEX I-IV) is (78 +/- 8) SNU (1 sigma). This is only slightly more than half of the expected rate. The significance of this deficit is assured - directly by the results from our two Cr-51 neutrino source experiments (at the 10% - level), and - indirectly by means of experiments in which Ge-71 is generated within the target solution from beta-decaying As-71 (at the percent level). GALLEX at Gran Sasso is now succeeded by GNO (Gallium Neutrino Observatory). The GNO status as of October 1998 is reported.
