NOAA 2673's hidden secrets revealed

Some additional and impressive images of the two strongest flares that NOAA 2673 produced.

The Sun is throwing a party!

The Sun is pushing its activity to still higher levels. On Sept 6, we could witness a very strong light flash on the Sun. Here on Earth, our radio, GNSS and PROBA2 team went wild because of the impact in their data!

Weather in space is picking up

The number of clouds hurling through space increased dramatically these last days. There is even one cloud heading into the direction of Earth. Fasten your seat belt.

The ultimate eclipse maker PROBA-3

In the near future, this duo-satellite will create solar eclipses just like the one we had on August 21 2017, but for more then 7 hours each day!

PROBA2 eclipse observations - first images online

PROBA2 did it: it saw the solar eclipse from its 750 km-high seat in space. PROBA2 captured this EUV-image with the moon partly covering the sun.

Night of the (shooting) Stars 2017 ***CANCELLED***

On 9 August from 21:30 to 24:00, the Royal Observatory opens its premises to the broad public to observe the night sky. Amateur astronomers will bring their telescopes to allow the participants a view on the stars.

NOAA 2665's fireworks continues!

NOAA 2665 was the source of a spectacular eruption on the Sun's farside on 23 July. A comparison is made with the 2012 event from exactly 5 years ago.

The Bastille Day 2017 event

NOAA 2665 continued to dominate the solar surface and was also responsible for the main event of the week, i.e. a long duration M2 flare associated with a halo coronal mass ejection on the French National Day.

A Sunday morning solar observing session

Solar observers had a great weekend observing and imaging the Sun, in particular with the rather large and dynamic sunspot group NOAA 2665 dominating the solar disk.

An eruptive surprize

The Sun surprized solar observers with a medium class solar flare on 3 July. The associated plasma cloud was not directed to Earth.
