... Many observatories around the world will follow these events, with the purpose of obtaining accurate measurements of the angular diameter of this red giant, from the recording of the lightcurve during the disappearance (or reappearance) behind the limb of the Moon. ... 6 November 1998: both disappearance and reappearance recorded under very good conditions at the TIRGO observatory by A. Richichi . ... A preliminary analysis confirms the findings of the previous event observed in February (see below)...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...
