We can see more CMEs with LASCO than
with earlier instruments because it's much more
sensitive. We can watch CMEs as they move far
into space and, because LASCO watches the Sun
nearly all the time, it can give us warnings
of all solar storms which are likely to hit
One day we hope to be able to predict accurately when CMEs are likely to erupt and travel towards Earth. This is important since the charged particles in CMEs can cause a lot of disruption to modern communications and power lines. Hundreds of CMEs have so far been seen by LASCO giving us a new and spectacular view of the Sun's behaviour.
