Temporal Correspondences in the Period 1905-2023 Between the Bradyseismic Trend at Campi Flegrei, the Periods of Lunar Culminations with Altitude Above 75° and the New Moons in Perigee Orbiting on the Boreal Segment Delimited by the Meridians +1° and +25°

The Campi Flegrei are an extensive volcanic area west of Naples subject to slow vertical deformation of the ground. The accelerations of the phenomenon which occurred in the periods 1950-1952, 1969-1972, 1982-1984 resulted in an overall uplift of just under 4 metres. It is shown how in the period 1905-2023 the most relevant ascending phases of phlegraean bradyseism, except two, took place during the periods of lunar Culminations with a Altitude greater than 75 degrees (Fig. 1B) after which the ground has decreased or more in general it has not undergone considerable changes: from 1905 to 2023, excluding the 1982-1984 and 2010-2021 windows, every period of lunar Culminations with a Altitude lower than 75 degrees can be aligned with an subsidence (Fig. 2). Two ascending phases do not align with the periods of highest Moons, but the first (1982-1984) was anticipated and accompanied by a peculiar sequence of 3 New Moons High in Super and Extreme Perigee orbiting at the peak of the sygytial phase over the Central Europe and the second took place during an configuration (extensive and unique) of some Elevated New Moons in Perigee over Italy (Fig. 3) in the central period (2013-2018) intermediate (2010-2021) to the two periods 2003-2009 and 2022-2028 with maximum Culminations (Fig. 1B). It is highlighted how the distribution over time of the 24 most relevant Moons, in gravitational and geometric terms (Fig. 3), corresponds to concomitant bradyseismic phases of proportionate importance. By far the most intense bradyseismic phase, that of 1982-1984, corresponds to the largest concentration of Major Moons and the most moderate and prolonged uplift phase (2005-2023) corresponds to an extensive distribution of "Central European" High New Moons in Perigee only Minimum. It is shown how these 24 Moons (which will be called Major Moons here as they are simultaneously the highest New Moons in the local celestial vault, the closest to the Earth and the most attractive because combined with the gravitational force of the Sun) are not to be considered isolated but always accompanied, before and after, by a harmonica of Elevate Moons in Super and Extreme Perigee.
