Abstract :
In the present work tweeks recorded at Indian low latitude ground station Allahabad (Geomag. lat. 16.05° N) during April 2007 to March 2008 have been used to study the occurrence characteristics, distance & reflection height in the Earth Ionospheric waveguide. Results shows that summer seasons has highest tweek occurrence ~63% and lowest for winter season ~18%. The tweek recorded having maximum mode n=6, tweeks with n=2 are more dominant with occurrence ~70%. Tweeks with n>;3 are more common during early night & maximum tweeks occurs in late night. Average distance traveled by maximum tweeks is in range of ~4000-8000 km.
