The Active Sun: SOHO Images
- SOHO-endorsed resources
- real-time movies! gif, mpeg
look at the Coronagraph (LASCO): can see the Sun move with respect to the stars
Note: the Sun's disk (drawn-on white circle) is about 0.5 degrees across
from which you can work out speeds...
- archived version of June 9, 2005 image
- sometimes planets come near the Sun in the sky:
conjunctions of
Mercury
Jupiter
...with a table of distances from the Sun,
you can work out speeds...
- Spectacular solar events:
look at proton showers and work out particle speed to Earth
similar storms (solar flares) also generate radio waves; these
can be converted into audio (like your radio does all the time)
and then you can hear them!
- movies of the Sun's disk show sunspots and can be used
to work out rotational period
