FAST TRACK PAPER: The SGR 1806-20 magnetar signature on the Earth's magnetic field

Mandea, M.; Balasis, G.

SGRs denote `soft γ-ray repeaters', a small class of slowly spinning neutron stars with strong magnetic fields. On 2004 December 27, a giant flare was detected from magnetar SGR 1806-20. The initial spike was followed by a hard-X-ray tail persisting for 380 s with a modulation period of 7.56 s. This event has received considerable attention, parti…
