Observers are reporting visual magnitude approaching 3.4, which is half-way between the out of eclipse average, close to 3.0, and the anticipated magnitude during totality, 3.8. Hopkins and Santangelo have begun to converge on JD 2,455,065 (+/- a few days) as the likely time of first contact (start of eclipse). Today being JD 2,455,127 (23 Oct), that was 62 days ago. At this rate, we'll bottom out in totality by JD 2,455,189 or slightly sooner - close to winter solstice. Jeff Hopkins predicts 2,455,183 for visual, and earlier in photometrically bluer wavelengths.
Fortunately, epsilon, Capella and the kids are rising earlier as winter approaches, making the effort to collect data of any kind easier on a person. Thus, I urge you to make that effort to get outside at least once a week, armed with eyes, camera, telescope or whatever you have, and report those estimates here at Citizen Sky, data link. We are scheduled to obtain interferometric measurements this season, and a good light curve will help put those observations in context. A posting about interferometry will be provided soon, but you can refer to the Citizen Sky videos recently posted for previews. Happy hunting!
