Three announcements from the Quo Vadis initiative

The Quo Vadis European Space Weather initiative is making the following three announcements.

Sun, Space, STCE, and Sangria!

The STCE will promote its educational and outreach activities at the 4th Symposium on Space Educational Activities in April 2022. Send in your abstract and join us there!

Elegy for a sunspot group

Decaying sunspot region NOAA 2871 managed to produce 2 M-class flares during its transit over the solar disk.

North and South

SILSO scientists have contributed to research extending the hemispheric sunspot number dataseries all the way back into the 19th century.

A prominence erupts

A well-sized quiescent prominence erupted around noon on 12 September near the Sun's northeast limb.

Increasing sunspot numbers

An increasing number of well-sized sunspot groups are dotting the Sun.

Rise of the solar flares

Solar flaring activity was on the rise last week. NOAA 2860 produced most of the 19 C-class flares as well as the sole M-class event, whereas tiny sunspot group NOAA 2859 was the source of the most photogenic eruption.

A filament goes kaboom!

A filament that was visible for nearly a week finally erupted on 22 and 23 August.

Days without sunspots

Despite the sunspot activity being on the rise, the Sun had a few spotless days late July and early August. This is not unusual.

Triumph of the coronal dimmings

Several coronal dimmings were observed last week in solar EUV imagery. Some of the associated CMEs were thought to have a potentially earth-directed component.
