A Carrington-like geomagnetic storm observed in the 21st century
Journal of Space Weather and Space Climate, 2015 In September 1859 the Colaba observatory measured the most extreme geomagnetic disturbance ever recorded at low latitudes related to solar activity: the Carrington storm.

Wavelet analysis of geomagnetic jerks [PDF]
, 2013 Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more

Localized fast flow disturbance observed in the plasma sheet and in the ionosphere [PDF]
, 2005 An isolated plasma sheet flow burst took place at 22:02 UT, 1 September 2002, when the Cluster footpoint was located within the area covered by the Magnetometers-Ionospheric Radars-All-sky Cameras Large Experiment (MIRACLE). The event was associated with

Characterisation of the temporal sequence of geomagnetic fluctuation of Xinmocun landslide
地球与行星物理论评Selecting an appropriate index is essential for the scientific and effective early warning of landslides. To explore the potential use of geomagnetic fluctuation signals as an early warning index for landslides, this study investigates the ...

Searching for Carrington-like events and their signatures and triggers
Journal of Space Weather and Space Climate, 2016 The Carrington storm in 1859 is considered to be the major geomagnetic disturbance related to solar activity. In a recent paper, Cid et al. (2015) discovered a geomagnetic disturbance case with a profile extraordinarily similar to the disturbance of the ...

Solar flares and variation of local geomagnetic field: Measurements by the Huancayo Observatory over 2001-2010 [PDF]
Serbian Astronomical Journal, 2017 We study the local variation of the geomagnetic field measured by the Huancayo Geomagnetic Observatory, Peru, during 2001-2010. Initially, we sought to relate the SFI values, stored daily in the NOAA's National Geophysical Data Center, with the ...

White light reduces flight height of birds in low‐density migration corridor
The Journal of Wildlife Management, EarlyView.We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.

Simulation study of near-Earth space disturbances: 1. magnetic storms
Progress in Earth and Planetary Science, 2019 A magnetic storm is the world-wide geomagnetic disturbance taking place in near-Earth space environment, lasting for a few days. Geomagnetic fields can be depressed by ~ 1% on the ground for large magnetic storms.
