DOI: 10.1007/s11207-021-01856-8
Abstract: Correlations between solar, interplanetary-medium parameters, and geomagnetic-activity proxies in 27-day averages (a Bartels rotation) were analyzed for the 2009 – 2016 time interval. In this analysis, two new proxies were considered: i) $B_{zs}$ GSM (Geocentric Solar Magnetic),… read more here.
