    As notified by Stellar Kafka (Director AAVSO) and Patrick Schmeer, the strange object KIC 8462852, more popularly known as Tabby’s star, has entered another fading event. This object has shown unusual and unpredictable fades picked up in Kepler data by citizen scientists. The cause of the fades is unknown and has been subject to wild speculation in the popular media, but the reality is more likely to be an unusual but interesting phenomenon such as a gas and dust cloud passing between ourselves and the star.

    This is a reasonably bright object at V magnitude of around 12 outside of a fade. So this can be a good target for both visual and CCD/DSLR photometry as well as low resolution spectroscopy.

    The object is located in Cygnus with coordinates (epoch=J2000):

    RA 20 06 15
    Dec +44 27 25

    The Variable Star Section, BAA Spectroscopy Database and AAVSO will all be interested in observations.

    Below is a plot of previous V magnitude observations submitted to the Variable Star Section database.

    Cheers,

    Andy

    Any mention of ‘Dyson Sphere’ fades will surely result in immediate expulsion from the VSS 😉

    I am completely with you there Gary! 🙂

    I think it is an interesting enigma but the evidence does not support any kind of intelligence. It could be an opportunity to help solve the puzzle using science, putting a stop to the unfounded speculation which has dominated some of the press.

    Cheers,

    Andy

    Gary and Andy you are now expelled for discussing the unmentionable!

    What have vacuum cleaners got to do with this? 🙂
