Join SANSA on Thursday 4 April 2024 at 18:00 for another exciting Space Talk by veteran space weather researcher from Canada, Donald Danskin. His talk is titled "Using Radio Waves to Monitor the Terrestrial Ionosphere". It will take place a SANSA Hermanus and live on Youtube
Summary of space weather conditions over the weekend (23-24 March 2024). A minor to severe geomagnetic (G1-G4) storm was observed with local Hermanus K index of 7 max. This was due to CME and coronal hole influences. Regular updates on spaceweather.sansa.org.za @SpaceweatherSA
An X3.3 solar flare has been observed with possible radio wave signal absorption in most part of the African region. SANSA @SpaceweatherSA continues to monitor space weather conditions on a 24/7 basis.
Time is running out to apply for the International Space Weather Camp 2024! Applications close on 11 February so do not delay. Final-year undergrad students can apply. To apply, follow this link: lnkd.in/giYj7Qu Please share this with your network.
Join us for the Meerkat @ 5 conference, 20-23 Feb 2024, Stellenbosch Celebrating transformational science, engineering, and human capacity development Read More ⬇️ sarao.ac.za/news/meerkat-5…
Although low confidence modeling of the CME related to yesterday's X5 flare event determined the possibility of shock influences near Earth early as 2 Jan. A minor geomagnetic storm watch valid 2 Jan is in place. swpc.noaa.gov/products/auror… for the Aurora-30 Minute Forecast model.
An official tracking model courtesy of SWPC is now available for the X5.0 flare event. They are in fact calling for the extreme western edge of the associated CME to pass Earth by January 2nd. Geomagnetic storming will be possible should an impact be observed as predicted.
An M5.7 flare was observed this morning from region AR3514. This caused total radio blackout on some parts on the African region with frequencies of up 35 MHz absorbed. This effect was even captured on our ionograms in Grahamstown and Hermanus. Stay tuned on @SpaceweatherSA
The SANSA Hermanus public tours will close today for the festive season. The tours will restart on Wednesday, 10 January 2024. Public Tours take place on Wednesdays at 11:00. Tours are free of charge, but bookings are essential at 028 312-1196.
The month was off to a stormy start when a series of geomagnetic storms, reaching G3/Severe levels, were observed on 1 December 2023. These storms were due to consecutive arrival of a few coronal mass ejections (CMEs) that left the Sun between the 27th and 28th of November.
[3:30 PM] Boitumelo Makobe A fourth CME was observed yesterday (28/11/2023) and behold It was a beautiful full halo CME associated with the M3.5 flare on 28/11/2023 19:32 UT. It is expected to be a direct hit impacting Earth late on the 1st into the 2nd of November.
It is midweek and the Sun has already surprised us with number of interesting events in the past 48 hours. Three CMEs were observed on 27/11/2023 and are expected to impact Earth from late 30/11/2023. Geomagnetic conditions may reach up G2/moderate storm due to these CME Impacts

☀ Been hearing about aurora sightings in recent months? It’s linked to the Sun’s activity, with a solar maximum expected this year. Find out more in the blog, or read this short thread 🧵
Asymmetrical halo CME produced by the M9 solar flare today. This is Earth directed with an impact likely within 72 hours. This could add to geomagnetic storming already forecast due to previous eruptions on Monday.
A strong solar flare (M9.8) was just detected around AR 3500 near center disk. A wave of plasma appears to be leaving the flare site, a good sign for a potential Earth directed eruption. SolarHam.com
A gorgeous eruption on Sun's northeastern (upper left) limb late on 26 October 2023. This was followed by a halo CME as expected, but it may not hit us because of the location too far away from Earth strike zone.

The M5.7 solar flare from AR3363 was highly eruptive and caused the first moderate S2 solar radiation storm of SC25. The resulting CME is impressive but we think the probability of it arriving at Earth is low due to the partial halo outline and location of the eruption.
The Sun emitted a strong solar flare on July 2, 2023, peaking at 7:14pm ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.0: go.nasa.gov/434EEFn
