We received the first data from PROBA2 of the September 1 annular solar eclipse. Again, PROBA2 was on the first row in space and therefore certain to witness it, clouds or not.
Submitted on 2016-08-30On 1 October 2014, communications with the STEREO-B spacecraft were interrupted during a planned test in anticipation of its solar conjunction at the Sun's farside (see image underneath for positions relative to Earth). Despite intense recovery efforts in the subsequent months, contact could not be re-established and the spacecraft seemed to be lost. More background information can be found in the news items of 4 June 2014 and 29 July 2015.

A high-speed solar wind emanating from a solar coronal hole reached the orbit of the earth with sparking firework on August 23-24 photographed from Franeker, the Netherlands.

The public was invited to search in the night sky for falling stars of the Perseids, a meteorswarm between the prestigious couples of the observatory in Uccle. It was a great evening on August 10.

It's the time of the year to catch falling stars. These are in facts meteors. A technique is developed at the space pool to listen and identify them. And, you can help!
Submitted on 2016-08-11Did the EUV space telescope onboard PROBA2 see the sun-grazing comet as a tiny dot on the solar surface lightening up? This is the story of 5 mysterious pixels.
Submitted on 2016-07-26Last week, NOAA 2567 continued its growth in magnetic complexity and sunspot area. Early on 21 July, this active region produced an M1.2 flare which was the first "medium" event since the M6 flare on 18 April this year by NOAA 2529 (see the 19 April news item). NOAA 2567 would produce a total of 7 M-class flares, the strongest being an M7.6 event on 23 July which was the most powerful since the M7.9 flare by NOAA 2371 more than a year ago (see this 5 August 2015 news item).
Submitted on 2016-07-19Forecasters seemed to be heading for yet another boring spaceweather week, when -during the afternoon hours of 14 July- a new sunspot region gradually developed about 70.000 km east of NOAA 2565's main spot. In solar terms, that's like shaking hands with your neighbours! The new "sunspot family" was numbered NOAA 2567, and both groups reached a surface area of nearly twice the surface area of the Earth by the end of the period.
Submitted on 2016-07-12Every year, the STCE publishes a news item with an overview of the most memorable solar and space weather highlights. These include spectacular solar flares, impressive filament eruptions, huge coronal holes, and much more. Each time, a movie is compiled with several clips of each event. As it also makes reference to the associated effects such as strong geomagnetic storms, aurora sightings, extremes in solar wind parameters, and number of strong flares, the news item provides at the same time a brief status of the ongoing solar cycle.
Submitted on 2016-07-06Once again, solar observers were treated on a blemishless golden orb, with the preliminary sunspot number being "0" from 25 June onwards. While the earth-facing solar hemisphere had apparently already left for the summer holidays, the Sun's backside still showed some signs of life, displaying a few active regions.
