Points Of Interest

SOHO telemetry keyhole #29. What is a Keyhole?  Click here  for more descriptive information.
SOHO will be in the keyhole period April 21 - May 3, 2010.  During this time, data that is
recorded on-board SOHO during the gaps in contact is delayed until it is dumped and transmitted
on a high-rate station.  This will be noted below as "temp data gap" periods.  The delay can
sometimes be a week long. So please bear with us.  For a DSN pass schedule  Click here.
