How are the solar flares from May 23, 2021 extraordinary? The Space Weather News for May 23, 2021 reads (with some highlighting by me)

Yesterday, the sun produced a sequence of solar flares unlike anything we've seen in years movie. Earth-orbiting satellites detected a dozen explosions in the magnetic canopy of sunspot AR2824. One of them emitted a radio burst so strong, it drowned out static from lightning storms on Earth and was recorded at midnight by listening stations in the Arctic. NOAA forecast models suggest that a CME might hit Earth's magnetic field on May 26th.

As non-expert of that field, I have a couple of comprehension questions:

What is a &quot;magnetic canopy of a sunspot&quot;? Is there a definition for that, or does it just mean &quot;magnetic flux tube coming originating at the sunspot&quot;?
Why is that solar flare so spectacular? Which parameters are the most extreme ones? Where could I find more on the statistics of those parameters? What exactly does &quot;in years&quot; mean here? How rare are which parameters of the May-23-flare?
How are sunspots named? A quick search showed that AR2824 seems to be around for quite a while, but I did find anything about whether that is a simple counter, or there are different prefixes, other than AR.
It is said that the &quot;CME might hit Earth's magnetic field&quot;, which is probably not same as &quot;it will hit Earth&quot;, or is it?  Could somebody please guide me how this is read from the (above linked) NOAA forecast model graphs? Do these models give a probablity of a CME reaching Earth? How likely is it that this CME might disturb any satellite?

In short: I would appreciate a quantified and expanded version of the quoted news, enriched with some definitions for the non-experts.

How are the solar flares from May 23, 2021 extraordinary?

They weren't at all extraordinary. The Sun has been quiescent for the last three or so years. This quiescence is typical of the period between solar cycles. Solar cycle 25 is finally becoming a tiny bit active.

What is a &quot;magnetic canopy of a sunspot&quot;?

Bad prose. An active region on the Sun is an area with an especially strong magnetic field.. Normally the magnetic field lines surrounding an active region are closed; they loop back toward the Sun. I guess one could call this looping the &quot;magnetic canopy of a sunspot.&quot; Occasionally the loops break. That break of the loop results in a solar flare or a coronal mass ejection.

Why is that solar flare so spectacular?

It wasn't. That active region resulted in 9 C class flares and 2 M class flares.
That's nothing compared to what we will see in a few years, and those in turn most likely will be nothing compared to the Carrington Event. The Sun is coming out of its solar minimum slumber.

How are sunspots named?

Sunspots are neither named nor numbered. Active regions on the Sun however are numbered, and have been since 05 January 1972. Active regions can have several sunspots, or none. The numbering of active regions is consecutive. The standard practice is to report only the last four digits and the date.

It is said that the &quot;CME might hit Earth's magnetic field&quot;, which is probably not same as &quot;it will hit Earth&quot;, or is it?

CMEs typically hit the Earth's magnetic field rather than the Earth. Only the very strongest CME's can punch through the Earth's magnetic field. People living at high latitudes might see some nice auroras (aurora borealis (northern lights), and aurora australis (southern lights) from this event.
When a CME hits the Earth's magnetic field, the field channels most of the particles around and away from the hitting the Earth. Some of the particles end up getting channeled toward the Earth's poles. This channeling of some of the particles toward the Earth's magnetic poles is why those auroras occur. Even something as strong as a Carrington-level event will have the greatest impact at high latitudes.
