摘要

2021年7月3日，太阳活动区12838在1418 UT发生了一次X1.5太阳耀斑，其X射线强度在~ 1429 UT达到峰值。它除了位于翼侧(~ 24°N, 88°W)外，对电离层也有较强的影响。GPS观测显示TEC增加了15-30分钟的延迟。在这次耀斑期间，大西洋上空还观测到短波无线电停电(强无线电停电)，这种情况在耀斑高峰时间后持续了一个小时。

Ionospheric Disturbances during X1.5 Class Solar Flare of 3 July 2021

An X1.5 solar flare occurred from solar active region 12838 at 1418 UT on 3 July 2021 and its X ray intensity peaked up at ~ 1429 UT. Besides its location at limb side i.e. ~ 24°N, 88°W, it had strong effects in the ionosphere. GPS observations reveal an increase of TEC with 15–30 minutes delay. A shortwave radio blackout (R3 - Strong Radio Blackout) over the Atlantic Ocean has also been observed during this flare that sustained for an hour after the flare peak time.
