Our Noctis-1 sensor is fully operational & monitoring satellites in orbit

We have published images taken this year by Noctis-1. This shows a @Starlink satellite in Low Earth Orbit, against a background of the Pinwheel Galaxy - 25 million light years away

Did you catch the Northern Lights this week? 🌌

Space weather has the potential to cause disruption on Earth. 🌍

@ESA's Vigil mission, designed & built by @AirbusSpace in Stevenage, will give advance warning of dangerous solar storms. 🛰️☀️

The National Space Operations Centre has released the October report on the threats from space-related hazards. 🛰️ 🌍

In October, there were:

➡️ 54 uncontrolled re-entries
➡️ 2,398 in-space collision warnings
➡️ 160 newly registered objects in orbit.

This week's heightened solar activity, which resulted in stunning aurora displays around the world, is a reminder of the serious issue of space weather and how it can affect key infrastructure, both on Earth and in space. 🌍

☀️A new era in space weather forecasting is beginning...

Last year, we saw an increase in solar storms that lit up the skies with stunning auroras across Europe.

However, these events can be disruptive, effecting power, satellites & communications. Space weather needs to be predicted early and accurately to give us the crucial time needed to protect satellites, astronauts and vital infrastructure on Earth.

That’s where our Vigil mission comes in.

Acting as a dedicated ‘space weather reporter’, Vigil will drastically improve our forecasting abilities with its specialised set of instruments.

There’s still time to submit an abstract to this year’s uk conference! The deadline has been extended to 1st June. We’d love to have a diverse agenda so if you’ve got something to share in the world of space weather I’d strongly encourage you to submit an abstract 😊☀️

[Met Office Space @MetOfficeSpace]

We recently provided techSPARK with a guest blog for their space editorial month which explores our cutting-edge work in space weather forecasting and technology.

But there is the serious issue of space weather.

The National Space Operations Centre – led by us and @UKSpaceCmd in partnership with @metoffice – monitors solar activity and provides notifications and advice to mitigate the risks of these events. ☀️
