TTSO5 notes…We regret we can’t attend this 5 th Trans-Tasman Symposium on Occultations and present IOTA-VTI to the occultation community and would hitherto wish to thank Dave Herald and Stephen Russell for stepping up to present the device on our behalf, and I’m sure both gentlemen will do a splendid job and aid in the continuing refinement of IOTA-VTI.
