Solar Radiometric Observations and Ionospheric Kinships by Space Overseer(s) at Limb-beaming Landau

Abstract

Strong varying intensity of solar activities impact near-earth space environments, magnetosphere, ionosphere, thermosphere as well as on the technological systems such as satellite communications, aircraft avionics, electrical power grids, and threats to human lives. Hence, it is essential to measure the phase of solar quietness as well as to monitor total flux using radiometric devices. This paper presents an analysis of Solar Flux and Sudden Ionospheric Disturbances (SID). Additionally, the paper further analyzes three magnetic storms that occurred during a 27-day Bartels period with 3-hour interval indices. These storms include E1 on March 31, 2001, which had a geomagnetically disturbed Kp of 9, and two magnetic storms with Kp ≥ 6 (E2 on April 8, 2001, and E3 on April 11, 2001). The events of 11 days of Solar Flux were observed in April 2001, within the frequency range of (245,15400) MHz with a peak of 143,671 SFU, under the supervision of the National Oceanic and Atmospheric Administration (NOAA). On March 25, 2008, NOAA's active region (AR) 10989 experienced peepholes due to a Coronal Mass Ejection (CME) of the M1.7 class flare. This event was reported chronologically to have a widespread index/imp rating of 5/2.
