Magnetic Flaring in the Pre-Main-Sequence Sun and Implications for the Early Solar System (2002, background): “During 1989–1997 (solar cycle 22), a period of about 3000 days, the GOES-7 satellite detected about 20 solar flares with 28:0 ergs s 1 logLXðpeakÞ 29:0 ergs s 1 in the 1.6–12 keV (1–8 Å) band (Sammis et al. 2000).”
Statistical properties of superflares on solar-type stars based on 1-min cadence data (2015, background): “2014), the typical sunspot area for generating X10 class flares (approximately 1032 erg) observed in 1989 to 1997 was 3 × 10−4 of the half area of the solar surface (Sammis et al. 2000), and the typical magnetic field strength of the sunspot is in the order of 1,000 G (e.”
MAGNETIC PROPERTIES OF SOLAR ACTIVE REGIONS THAT GOVERN LARGE SOLAR FLARES AND ERUPTIONS (2016, background): “This result is in line with previous results that the δ-spots have higher flare productivity (e.g., Sammis et al. 2000).”
Can Superflares Occur on Our Sun (2012, background): “Figure 2 (filled circles) shows an empirical relation between the spot size and the X-ray intensity of solar flares (Sammis et al. 2000; T. T. Ishii et al. 2012, private communication).”
