December 2019 officially marks the start of the new solar cycle

SILSO pinpointed the timing of minimum solar activity. With this new information, solar physicists from NASA, NOAA and SILSO will refine the prediction of the next milestone of the new cycle: its maximum. 

Adieu filament!

A filament in the northeast solar quadrant erupted early on 31 August. Severeal ground and space based observatories recorded the event, showing it from different angles and with various filters.

Geomagnetic storm

Geomagnetic activity reached minor storming conditions on 28 and 31 August. So far in 2020, there have been only 4 days with such levels of geomagnetic turmoil.

Solar cycle minimum

SILSO has announced on their website that solar cycle minimum most likely took place in December 2019, with full confirmation expected in the coming months.

Spotless, not powerless

Two interesting eruptions took place during the weekend of 15-16 August. The C2 and B1 x-ray flares took place in two different, spotless regions and were both associated with a coronal mass ejection.

C-class flare!

On 8 August, a C1.5 flare erupted in sunspot region NOAA 2770. The gradual increase in flaring actvity and in the number of new solar cycle sunspot groups during the last few months confirms we are slowly exiting solar cycle minimum.

A prominence erupts

A prominence near the southeast solar limb erupted on 31 July. The associated coronal mass ejection (CME) was not earth-directed.

The tale of a comet's tail

Comet NEOWISE gave an impressive evening spectacle during the first few weeks of July, being visible with the naked eye and displaying two distinct tails.

A new member of the new solar cycle

A new sunspot has rounded the solar east limb. It belongs to the new solar cycle, which seems to have started late in 2019.

First images by Solar Orbiter

During an ESA online press briefing on 16 July, the first images from ESA’s new Sun-observing spacecraft Solar Orbiter have been released. The images are very exciting, and promise to get only better and to reveal new scientific insights!
