Abstract

For remote identification of the processes of powerful solar activity in the form of CME directed towards the Earth, a technique of flicker noise spectroscopy has been developed. The results of the analysis of geo-effective events (> G1) are presented according to the data of the international network of neutron monitors and the multidirectional muon hodoscope URAGAN, which indicate the appearance of predictors (with an outstrip of 1–2 days) of the CME approach to the Earthʼs orbit.

2. Fig. 1. Analysis of the event 14.06.2008. Total series of the nonstationarity factor C(t) for NMs of different continents (units): for European (LMKS, MOSC) (a), Asian (AATB, NANM) (b), American (MXCO, CALG) (c), sum for all NMs (d), Kp index values (e). Data (a, b, c) are shown for the 08-14 June interval as predictors. Data (d) correspond to the appearance of ‘spikes’ after the predictor (15-17 June) during the forebush effect. The abscissa axis is the time interval 08-18 June 2008

Analysis of the event 04.11.2021: the C(t) sum of seven NM series (CALM, JUNG1, LMKS, AATB, YKTK, MXCO, NEWK) (a), C(t) series for the sum and product of the three ‘ring’ series of the URAGAN yearscope (units) (b, c). Data (a, b, c) are shown for the interval 28 October - 03 November as predictors. Data (d, e, f) correspond to the appearance of ‘spikes’ after the 03-05 November predictor during the forebush effect. The abscissa axis is the time interval 28 October - 05 November 2021
