Abstract
We have studied solar activity and space weather conditions during multiple planetary conjunction periods ( MPC) as observed from Earth during the years 1850-2000 AD. Significant decreases in sunspot activity and solar 10.7 cm radio flux and absence of severe space weather conditions is found during most of these MPC . Possible planetary influences in longitudinal organisation of sunspot activity is suggested by these results. The success of major space missions ( lunar and human) during MPC is also noticed during 1957-2000 AD. The applications of the above results include: short term space mission planning and inference/prediction of solar-terrestrial conditions during multiple planetary conjunction periods.
