Extremely Severe Space Weather and Geomagnetically Induced Currents in Regions with Locally Heterogeneous Ground Resistivity

Edited by: S. Fujita, R. Kataoka, I. Fujii, and A. Pulkkinen and S. Watari

The geomagnetically induced current (GIC) in the middle and low-latitude countries has been assumed to cause no serious damages on infrastructures on the ground. However, nobody has estimated how large the GIC would be in these countries during extremely severe geomagnetic storms like the Carrington storm in September 1859. Furthermore, the locally heterogeneous ground resistivity, which may unexpectedly boost local GIC intensity, has not been treated in the previous GIC studies.

Therefore, it is an important problem for scientists studying magnetic field variations in space and on the surface of the Earth to evaluate the extreme GIC in these countries.

    Global MHD simulation of magnetospheric response of preliminary impulse to large and sudden enhancement of the solar wind dynamic pressure

    A sudden increase in the dynamic pressure of solar wind generates a prominent and transient change in ground-based magnetometer records worldwide, which is called a sudden commencement (SC). The magnetic field...

    What caused the rapid recovery of the Carrington storm?

    The geomagnetic storm during the Carrington event, which occurred on 2 September 1859, displayed extremely rapid recovery. The geomagnetic field increased by approximately 650 nT/h at Bombay, India, and by >30...

    Statistical properties of superflares on solar-type stars based on 1-min cadence data

    We searched for superflares on solar-type stars using Kepler data with 1-min sampling in order to detect superflares with a short duration. We found 187 superflares on 23 solar-type stars whose bolometric ener...
