Talking about solar activity, it may affect spacecraft with its radiation storms. When there is a strong space radiation storm that can har satellites, launches might be delayed. It his can also be the case with strong solar flares that could interfere with communications. In orbit satellites can have issues due to strong space weather. Some satellite orbiters push satellites to a lower orbit to prevent damage. Low orbit satellites don’t have much effect, higher orbit satellites are in more danger during strong space weather events. For example on the LASCO imagery you can see the images with many white sparks due to incoming particles on the sensor.

Planned for launch in 2025 ESAs Lagrange Mission will probably be our next side view of the sun once the Stereo A mission ceases to be of value. Also, I`d like to mention Parker Solar Probe impressed me really how it was manufactured to resist high temperature.The space craft which is capable to take samples from the outer corona of the Sun really makes you amazed by it, because of the high temperature it can endure. So looking forward to the new mission to the Sun.

They will have to visit at night when it will be not so hot?

Have you ever heard that solar activity has a huge impact on our technology. Our technology in space, to our technology on the ground, historical evidence shows the vulnerability of modern technology when confronted with high energy particles, a by-product of space weather events. Equally important is to remember that space weather has a global footprint, thus the damage is felt worldwide rather than local, much like an outbreak. Impact on satellites, aviation, power grid, navigation and communication systems have all been previously documented.

GREEN OCEAN SPRAY: There's a first time for everything. Aurora tour guide Marianne Bergli of Tromsø, Norway, has seen just about every shape, form and colour the Northern Lights have to offer. But over the weekend she witnessed something new. Green ocean spray:

Have you heard that the Earth’s climate is heavily affected by the amount of energy radiated onto Earth by the sun. The amount of radiation from the sun influencing Earth and the way in which this radiation is distributed across the various seasons and latitudes around the Earth, is directly influenced by changes in solar activity. This piece of information I`ve found on the web of uk space news.

What are satellites used for? Find out why launching satellites is so important and how can world benefit from using satellite imagery and data with recent case studies.

Also, I found there an information with more details about the real danger of solar activity and why the Sun`s activity must be monitored.

AURORA SURPRISE: A stream of solar wind hit Earth on Jan. 25th. The impact sparked an unexpected G1-class geomagnetic storm. "Suddenly, the whole sky was moving and dancing. It felt like aurora was hitting us with a hammer onto the head," reports Markus Varik, who sends this picture from Tromsø, Norway:
