A recent eruption on the far side of the Sun looks to be science gold.
A huge coronal mass ejection exploded on the far side of the Sun, causing a radiation storm across the Solar System. There was a type of hot gas that could be seen around the Sun.
Sometimes this means that the CME is on its way to earth. The eruption was on the far side, so we won't see the effects of a solar storm here.
Venus was in the path of the storm and with it, the Solar Orbiter, a space probe run by the European Space Agency and NASA that is currently near Venus after a September 4 gravity assist.
This has given us the chance to observe and measure a huge, farside CME, something that is usually difficult for us to do.
This isn't a run-of- the-mill event. Many science papers will be studying this for a long time.
The Sept. 5th event is one of the largest Solar Energetic Particle storms that we have seen so far.
It's not clear where the Sun erupted from, but it's possible that the culprit is a sunspot region called AR 3088, which rotates behind the disk of the Sun at the end of August.
SOLAR DISCO: AR3088 is stayin' alive - blasting out light and matter on its journey around the Sun. It's still providing an amazing show even out of our view. Here is a look at the region over 2.5 days ending with its big M2 blast directed away from us. SDO 171/193/131 ๐ง๐๐คฉ๐๐ pic.twitter.com/lXGiUQC3Os

A huge M2 class flare was left as it did so.
The study of internal oscillations of the Sun can be used to detect sun spots on the far side.
Sound waves bouncing around inside the Sun can be affected by the amount of magnetic fields.
After it left the side of the Sun, NASA suggests that it may have grown.
It's relatively quiet on the Earth-facing side of the Sun compared to the recent action with AR3088. A large eruption recently occurred on the far side. A likely candidate, ole' AR3088. Helioseismology shows a big region. Probably our old friend. ๐ง๐๐๐ pic.twitter.com/fjp97I4Sp2

There are many spaceships that may not survive the Sun buffet. Solar Orbiter was built to survive a solar onslaught.
It has instruments to measure solar phenomena.
Just prior to the gravity assist maneuver, Solar Orbiter was in the path of an earlierCME.
There was a significant increase in solar energetic particles. Scientists can use this information to better understand the behavior of the Sun and how it affects the space environment.
The high-energy particle intensities remain high; and looks like an interplanetary shock just passed through @ESASolarOrbiter early today. CME should be following soon. pic.twitter.com/yF5njp5QRu

If AR 3088 reappears, it won't do so for a while. It is possible that it will be smaller and quieter when it returns to us.
There is no solar storms on the horizon at the moment.
There are a few sunspot regions that can be seen, but they all seem to be fairly subdued for the time being.
We should expect more powerful eruptions in the not-too- distant future because the Sun is getting into the peak of its activity cycle.
You can follow the British Met Office, the Australian Bureau of Meteorology, and the Space Weather Prediction Center if you want to stay on top of solar weather forecasts.
