Stormy space weather ahead

Yesterday's M1.2 solar flare from departing sunspot region 3413 produced an impressive partial halo coronal mass ejection which is likely to arrive at our planet on Monday, 4 September. pic.twitter.com/8cYPF9v6Qc

The resulting coronal mass ejection from yesterday's M1.2 solar flare was fairly wide despite the bulk of the ejecta heading mostly west of our planet. We do expect an impact from this plasma cloud at our planet on 4 September, Monday which could cause minor storm conditions. This would be the second coronal mass ejection to arrive at our planet as a fainter partial halo coronal mass ejection was launched on 30 August due to a filament eruption.

While it is hard to analyze the data, this coronal mass ejection could have arrived last evening despite it was expected to arrive later today. We already had a period with minor G1 geomagnetic storm conditions and it is hard to say if this is it or we should expect an impact later today. As always keep an eye on the data as we finally have a period with more stormy space weather conditions to look forward to.
