Dip update 97/n

[Orig: Oct 3, 2017]

Hi everyone,

Below is the LCO light curve as of 3 October. As you can see, the last reading from OGG could indicate it is beginning a new drop - but only at the 2-sigma level ("2 sigma level" means that the data point deviates from the normal flux by twice the extent of its error bar. We refer to something as statistically significant when the deviation is at the 3-sigma level, i.e, when the data deviates by 3 times its measurement error). Excited to see what tonight will bring!

NB, I have now remove the spurious point taken at TFN on September 28, as previously noted, it was based on only one pointing (4 images), and I believe that its error bars were seriously underestimated.

All the best,

~Tabby and team

PS: These observations are happening because of the wonderful backers of our 2016 Kickstarter project. The Kickstarter campaign has ended, but we are still accepting donations to purchase additional observing time on the LCO 0.4m network. Thanks in advance for your support!
