Abstract: We study the manner in which solar and interplanetary characteristics correlate with geomagnetic indices during solar cycle 25's ascending phase. Solar cycle 25's ascending phase's sunspot number, interplanetary magnetic field, and geomagnetic indices are all related to that of cycles 22, 23, and 24. There is a periodic in the sunspot number, geomagnetic parameters, and interplanetary parameters (IMF). However, during solar cycle 25's ascending phase, the IMF and geomagnetic parameter values differ. We determined that all of the geomagnetic parameters, IMF, and sunspot number were in good agreement. This phase has unique minimum and maximum durations. Compared to the ascending phase of solar cycle 25, the cosmic ray intensity magnitude was lower during this ascending phase. We discovered that the geomagnetic indices, sunspot number, and IMF all show larger spectrum fluctuations than at the start and finish of the cycle. These factors have a continuous spectrum energy of medium to week magnitude, according to our analysis & three different neutron monitor Oulu, Moscow and Athens are observed the highest peak down in year of 2020 in the ascending phase of Solar Cycle 25. We propose that solar activity plays a role for the unique circumstances of solar and interplanetary parameters as well as geomagnetic indices.

Key words: Sunspot number, interplanetary parameters (IMF), geomagnetic index.
