At least two objects, which a combined width of perhaps several thousand feet, are headed directly toward Earth at around 1 million miles per hour, from the direction of Tabby's star. Traveling at this rate, you can expect them in around a month. This first silhouette of the objects was captured on March 5, 2011. At this time, the objects were so far away, they were observed as a single spot between us and Tabby's star.
By February 28, 2013, the cluster had gotten close enough that they began to appear as separate objects.
Then by April 17, 2013, they got close enough to separate and reflect light from Tabby's star, resulting in an apparent increase in brightness, above anything possible from the star itself, from the direction of the star. The increase in brightness above 100 around 1550 indicates a large smooth surface on the object, parallel with its path of approach from the direction of Tabby's star.
Assuming a speed of about 1 million miles per hour, and a combined width of half a mile, these two objects would have been blocking light from an area of Tabby's star about 287,000 times their actual size. This put them about 0.005159 light years, or about 3.4 years away at the time the second silhouette was captured. Meaning they should be getting here pretty soon.
There can be no doubt, based on the increase in detail between the three silhouettes, that these objects are getting closer. There can be no doubt, based on the fact that they keep blocking the same star at different distances, that they are headed directly towards us. There can be no doubt, based on the reflection of light to more than 100% of what Tabby's star can produce, that they are pretty close.
