3 Magnetars: A Short Review and Some Sparse Considerations

Fig. 3.3 The 2004 December 27 giant flare of SGR 1806–20 as observed by RHESSI (from Hurley
et al. [112]). Panel a shows the 20–100-keV light curve. The (saturated) spike is at ∼30 s and the
inset shows the profile of a bright burst the preceded the flash by ∼2 min. The modulation at
the spin period of SGR 1806–20 (7.5 s) is apparent. Panel b shows the temporal evolution of the
spectral temperature
