Delay analysis

TSSA and CTSI shows delay or lag wrt each other1,3,5. Solar cycle data (21,22,23) is used in the analysis and possible correlation between H alpha flare index and delay is worked out .It is found that these two parameters are anti correlated with a correlation factor of 0.8 9427 . The 27day solar activity shows heighest correlation factor. A new parameter called delay index number (DI) is defined.This paramter shows two sharp peaks wrt delay event number ,during the span of solar cycle 21,22,23. The peaks fall in soalr quite period 1986 and 1996. Thus D I acts as an indicator of quite phase (ie solar minima )of sun.The possible cause for sharp shoot up is under investigation.
