It is well known that whenever a Ground level enhancement (GLEs) is recorded it is of great importance to issue an automatic Alert, since a GLE event could affect the reliable operation of technological systems and have an effect on human health as well. In this sense, an update GLE Alert system named GLE Alert ++ is released by Athens Neutron Monitor Station (ANeMoS) and provided through ESA Space Weather Network. The main core of this new system is based on the previous one GLE Alert Plus while significant improvements concerning its software design and functionality have been implemented. The fully parameterizable interface of this GLE Alert system gives the ability to the administrator to set the parameters undependably for every station, to design a running scenario, trimming all the parameters of GLE Alert system and to decide which station will be involved in the scenario. For the first GLE of the Solar Cycle 25, GLE73, which took place on 28 October 2021 and recorded by several stations of the worldwide ground-based neutron monitor network an accurate alert was issued successfully by the new GLE Alert ++ System.
