Although fairly quiet an average of two or more echoes per minute have been seen most mornings lately. In today's screenshot the NW Hampshire H Pol receiver sees two echoes only one of which is seen by the co-located V Pol receiver. The very feint echo observed by the Norman Lockyer receiver is most likely the same one seen on both the NW Hampshire receivers while Armagh saw neither. The upper echo seen by the Norman Lockyer receiver appears to have been unseen by any of the other receivers. So once again the observations show that the echoes are directional and linearly polarised despite the incident illumination being Right Hand Circular Polarised. Improvements we are working on will enable accurate correlation of echoes received at the different locations but this will be achieved by post processing as it isn't practical to do so on the live displays. There is guidance on using the system at and more notes are available at ? Brian
