Conclusion
The apparent speed and direction of the ionospheric drift by the simple similar fades method are not significantly altered by more detailed calculations of the time shift by optimum cross-correlation method between the records from pairs of antenna. The predominantly westward direction of drift at Thumba and large speeds may be taken as real.
