*ACTIVE SUNSPOT:*It is 200,000 km long and crackling withM-class 
<https://spaceweather.com/glossary/flareclasses.html>solar flares. We're 
talking about sunspot AR2965. This morning in Malaysia, Karzaman Ahmad 
photographed the sprawling active region from the Langkawi National 
Observatory:

AR2965 has an unstable 'beta-gamma' magnetic field. Between the 
sunspot's many dark cores, patches of north and south magnetic polarity 
are pressed together, creating conditions ripe for explosivemagnetic 
reconnection <https://en.wikipedia.org/wiki/Magnetic_reconnection>. As a 
result, we have seen M-class solar flares3 out of the past 5 days 
<https://spaceweather.com/images2022/15mar22/3outof5.jpg>.

So far, the explosions have not hurled any significant CMEs toward 
Earth. Their primary effect has been to cause a series of minor 
shortwave radio blackouts. Mariners, aviators, and ham radio operators 
may have noticed unusual propagation at frequencies below 20 MHz.*Solar
