We present the first Fermi-Large Area Telescope (LAT) solar flare catalog covering the 24th solar cycle. This catalog contains 45 Fermi-LAT solar flares (FLSFs) with emission in the γ-ray energy band (30 MeV–10 GeV) detected with a significance of ≥5σ over the years 2010–2018. A subsample containing 37 of these flares exhibits delayed emission beyond the prompt-impulsive hard X-ray phase, with 21 flares showing delayed emission lasting more than two hours. No prompt-impulsive emission is detected in four of these flares. We also present in this catalog observations of GeV emission from three flares originating from active regions located behind the limb of the visible solar disk. We report the lightcurves, spectra, best proton index, and localization (when possible) for all FLSFs. The γ-ray spectra are consistent with the decay of pions produced by >300 MeV protons. This work contains the largest sample of high-energy γ-ray flares ever reported and provides a unique opportunity to perform population studies on the different phases of the flare and thus allowing a new window in solar physics to be opened.

我们展示了第一个涵盖第 24 个太阳周期的费米大面积望远镜 (LAT) 太阳耀斑目录。该目录包含 45 个 Fermi-LAT 太阳耀斑 (FLSF)，在γ射线能带 (30 MeV–10 GeV) 中发射，检测到的显着性≥5 σ在 2010-2018 年间。包含 37 个这些耀斑的子样本在瞬发硬 X 射线相位之后表现出延迟发射，其中 21 个耀斑显示延迟发射持续了两个多小时。在其中四个耀斑中没有检测到瞬发脉冲发射。我们还在这个目录中展示了来自三个耀斑的 GeV 发射观测，这些耀斑源自位于可见太阳盘边缘后面的活动区域。我们报告了所有 FLSF 的光曲线、光谱、最佳质子指数和定位（如果可能）。的γ射线光谱与通过> 300兆倍电子伏的质子产生的介子的衰变是一致的。这项工作包含最大的高能γ样本-射线耀斑曾经报道过，并提供了一个独特的机会来对耀斑的不同阶段进行群体研究，从而打开太阳物理学的新窗口。
