What changed due to 2017 May Dip?
Time and timing
|Dips during the second big dip period between d 1518 and d1570 |
|The dip has about 98% at peak dipping. (Source: Jason Wright, Twitter)|

Which Hypothesis get stronger, which one loose?
- A object in our local solar system: This seems not to be the case, given the periodicity of 2 years and the knowledge of our solar system. Hypothesis gone!
- A cloud in the interstellar medium (ISM) in between us and the star. Due to repeated measurement of the signal very low possibility. Hypothesis not worth to mention any more!
- Black hole, Hypothesis gone!
- Comets: This is a tricky one, there are no new supports to a comet, but an other observation should here be mentioned: Beside the new dip event, it seems, that the star is still under a global dimming regime as observed by large telescopes. This could hardly be explained by comets. Hypothesis very low chance!
- Planet collision: The big question is, where is the infrared signal! Hypothesis very low chance!
- Star is changing its behavior: We have no model, how a star of that size and age could do that, in addition, the new dip does not support this hypothesis. Hypothesis gone!
- Something we have not thought about
- Very special thin dust cloud (ring structure) interacting with a magnetic field
- Large scale Dyson structure of unknown shape (not very good matching the data)
- Star lifting by natural or artificial cause (My favorite)
