Fig. 3From: Severe L-band scintillation over low-to-mid latitudes caused by an extreme equatorial plasma bubble: joint observations from ground-based monitors and GOLDUpper panels (a–c): OI 135 nm images measured by GOLD on March 13–14, 2022. The images exhibit extreme EPBs reaching latitudes larger than that of Puerto Rico (green X). Lower panels (d–f): OI 135 nm images measured by GOLD on March 14–15, 2022. The observations on March 14–15 are shown for comparison purposes and exhibit more typical latitudinal extents of the EIA and the EPBsBack to article page
