this article from june 26 spaceweather:
life without soho: the solar and heliospheric observatory (soho) won't be
sending images of the sun to earth for the next 18 days due to a problem with
the spacecraft's high-gain antenna. what will we do? space weather forecasting
will go on much as before: daily images of the sun and sunspots are available
from ground-based observers. coronal holes (which spew solar wind streams that
trigger auroras) and solar flares will continue to be recorded by various noaa
satellites.
nevertheless, soho will be missed: without soho's coronagraph images, coronal
mass ejections (cmes) can leave the sun undetected and sweep past earth with
little warning. geomagnetic storms resulting from such impacts could take us by
surprise. holographic images of the sun's farside will also be unavailable
during the 18-day blackout. there will be no advance warning of big sunspots
before they appear on the earth-facing side of our star.
