The maximum phase of the solar cycle is characterized by several interestingfeatures in the solar activity, heliospheric characteristics and the galacticcosmic ray (GCR) intensity. Recently the maximum phase of the current solarcycle (SC) 24, in many relations anomalous when compared with solar cycles ofthe second half of the 20-th century, came to the end. The corresponding phasein the GCR intensity cycle is also in progress. In this paper we studydifferent aspects of the sunspot, heliospheric and GCR behavior around thisphase. Our main conclusions are as follows: 1) The maximum phase of the sunspotSC 24 ended in 06.2014, the development of the sunspot cycle being similar tothose of SC 14, 15 (the Glaisberg minimum). The maximum phase of SC 24 in theGCR intensity is still in progress. 2) The inversion of the heliosphericmagnetic field consists of three stages, characterized by the appearance of theglobal heliospheric current sheet (HCS), connecting all longitudes. In twotransition dipole stages beside the global HCS there are additional local HCSs,while the inversion stage lies between two transition dipole ones and there isno global HCS in this stage. The inversion stage of the current SC 24 is thelongest when compared with those for SC 21-23. The second transition dipolestage and hence the whole inversion period of the heliospheric magnetic fieldin SC 24 provisionally ended in 08.2014. 3) The behavior of the GCR intensityin the period of the sunspot maximum phase and the inversion of theheliospheric magnetic fields for SC 21-23 demonstrates all the characteristicfeatures for this period: the two-gap structure corresponding to two-peakstructure in the sunspot activity, and the energy hysteresis. In the current SC24 the GCR intensity shows rather unusual features and we should wait for oneor even two years to see the whole picture.
