SANSA Space Weather

A coronal mass ejection (CME) has struck Earth! This CME lifted off the Sun between the 17th and 18th of March 2026 and arrived at Earth late last night (about 22:19 SAST), causing G2-G3/Moderate to Strong storms (Kp 6-7). More storms are expected! Stay tuned for more updates!

WARNING/ALERT: Another G2/Moderate storm interval with Kp of 6 was observed due to the ongoing high-speed stream influences from coronal hole 31 (CH31/+). Solar wind speeds are at strong levels, reaching up to 650 km/s. Stay tuned to @SpaceweatherSA for more updates ☀️

WARNING/ALERT: Geomagnetic conditions are at G2/Moderate storm levels with Kp of 6 due to the ongoing high-speed stream influences from coronal hole 31 (CH31/+). Solar wind speeds are at strong levels, reaching up to 700 km/s. Stay tuned to @SpaceweatherSA for more updates ☀️

@NNMaphitha Last week there was some activity, a geomagnetic storm was in effect on the 15th and 17th of February see figure below, however; these were just minor storms. Geomagnetic storms usually affect high frequency communications.

@SpaceweatherSA Hi there. Is there a geo storm currently affecting network frequencies? All networks have been struggling for signal this and the past week.

WARNING/ALERT: Geomagnetic conditions are at G1/Minor storm levels with Kp of 5 due to the ongoing high-speed stream influences from coronal hole 24 (CH24/+). Stay tuned to @SpaceweatherSA for more updates

WARNING/ALERT: An X-class flare is currently in progress! Frequencies of up to 27 MHz may be affected. Stay tuned to @SpaceweatherSA for more updates☀️

WARNING/ALERT: A G1/Minor geomagnetic storm is currently in progress with a Kp of 5. This is due to HSS influences from CH17. Stay tuned @SpaceweatherSA for more updates.

Absolutely stunning footage of last night’s geomagnetic storm as seen from the ISS. Russian cosmonaut Sergey Kud-Sverchkov said it was like flying straight through them.

Current geomagnetic conditions are at G3/Strong (Kp=7) levels. Stay tuned to @SpaceweatherSA for more updates☀️ @SANSA7 @dstigovza @SABCNews #spaceweather

Geomagnetic conditions are now at G4/Severe (Kp=8) storm levels! Stay tuned to @SpaceweatherSA for more updates☀️ @SANSA7 @dstigovza @SABCNews #spaceweather

Another G3/Strong geomagnetic storm is in progress. Stay tuned to @SpaceweatherSA for more updates @SANSA7 @dstigovza #spaceweather

Geomagnetic activity update. 🌞 @SANSA7 @SpaceweatherSA @dstigovza #geomagneticstorms #spaceweather

Earth is in a moderate geomagnetic storm of Kp 6. The solar wind is strong, reaching 900 km/s. The local Hermanus K index is showing a strong storm (K index=7). Stay updated on space weather activity by visiting spaceweather.sansa.org.za/products-and-s….

Local Hermanus (South Africa) geomagnetic conditions reached extreme levels (K-index 9) at 02:00 Local Time due to a coronal mass ejection (CME) impact at Earth! Stay tuned for more space weather updates!

The expected geomagnetic storm has arrived at G4/Severe conditions. The geomagnetic storm is expected to continue throughout tomorrow (Tuesday, 20 January) with G1 to G3 conditions and a possibility of further G4/Severe storm levels. Read more here: shorturl.at/NlmVL

WARNING/ALERT: A G4/Severe geomagnetic storm is in progress with a maximum Kp of 8 due to a CME impact. Stay tuned to @SpaceweatherSA for more updates. @SANSA7 , @dstigovza

The South African National Space Agency (SANSA) has put out a warning for elevated geomagnetic storm activity to affect the Earth on Tuesday. tinyurl.com/598u3k9s
