2019 年 2 月 8 日，大气-空间相互作用监测仪在波多黎各东北部闪电的初始击穿阶段观测到地面伽马射线闪光 (TGF) 和正云内 (+IC) 闪电产生的精灵。 456 毫秒后，在第一个闪电以南约 300 公里处观察到由负云对地 (−CG) 闪电的回击 (RS) 产生的第二个精灵。无线电测量表明，短 (30 μs) 和大 (280 kA km) 高能云内脉冲 (EIP) 产生了第一个 Elve 的电磁 (EM) 波，而 -CG 的 RS 是第二个 Elve 的电磁源。假设 EIP 和 RS 是 777 nm 发射的来源，则相对于紫外线脉冲的延迟以及 777 nm 发射的形状和持续时间都可以通过云内的散射和吸收来解释。 +IC 闪电产生的 TGF 的持续时间与 EIP 相同（~30 μs）。由于 TGF 的 ±80 μs 时间不确定性，我们只能说 TGF 是在 EIP 之前或很可能与 EIP 同时产生的。 777 nm 的大脉冲表明大部分 EIP 是由热通道中流动的电流产生的，但 TGF 电流也可能对 EIP 产生显着贡献。
On February 8, 2019, the Atmosphere‐Space Interaction Monitor observed a terrestrial gamma‐ray flash (TGF) and an Elve from a positive intracloud (+IC) lightning during the initial breakdown stage of a lightning flash north east of Puerto Rico. A second Elve produced by the return stroke (RS) of a negative cloud‐to‐ground (−CG) lightning was observed 456 ms later about 300 km south of the first one. Radio measurements show that a short (30 μs) and large (280 kA km) energetic in‐cloud pulse (EIP) produced the electromagnetic (EM) wave for the first Elve while the RS of the −CG was the EM source for the second Elve. Assuming that the EIP and the RS were the sources of the 777 nm emissions, both the delay relative to the ultra‐violet pulse and the shape and duration of the 777 nm emissions can be explained by scattering and absorption inside the clouds. The TGF produced by the +IC lightning had the same duration as the EIP (∼30 μs). Due to the ±80 μs timing uncertainty of the TGF, we can only state that TGF was produced just before or most likely simultaneously with the EIP. The large 777 nm pulse indicates that a large part of the EIP was produced by a current flowing in a hot channel, but it is likely that the TGF current also contributed significantly to the EIP.
