  A radio-IR-optical-X-ray observation campaign of SS 433 has been performed in
April 2006, when the jet axis is almost perpendicular to the line of sight.
Five flares have been detected during the campaign by radio monitoring
observation with RATAN-600. The X-ray astronomical satellite Suzaku observed
the source in and out of eclipse. In the X-ray data out of eclipse, the flux
shows a significant variation with a time scale of hours. The source seems to
be in the active state during the campaign. The observation logs and
preliminary results are presented.
