Vrlo zanimljivo! :286: :hopla:

Svi se mi potajno nadamo da su tu u pitanju nekakvi alieni! :mrgreen: Ali, upravo zato što se nadamo, i zato što smo već predugo sami na ovom kamenčiću, ne prihvaćamo ništa manje od 200 postotnog dokaza za to, jer želimo činjenice, a ne nekakve priče za laku noć, kojih imaš iza svakog ćoška, na lopate. :286:

AAVSO Alert Notice 542
April 8, 2016

Continuing observations requested for KIC 08462852


Further to AAVSO Alert Notice 532
(https://www.aavso.org/aavso-alert-notice-532), the AAVSO is
requesting ongoing time-series observations of the enigmatic
variable object KIC 08462852 (= KIC 8462852) beginning immediately
and continuing through at least the end of 2016.

Details on KIC 08462852 (V=11.88) were given in Alert Notice 532.

Observations are requested in order to study not only the aperiodic
fading events but also the behavior of the star outside of these
events.

Filtered time-series observations in one or more photometric filters
are encouraged. Individual fading events have lasted for several
days each, but show complex structure on very short timescales. The
star itself is also rotating, and shows rotational variation at the
millimagnitude level with a period of 0.8797 day.

Coordinates:  R.A. 20 06 15.46  Dec. +44 27 24.8   (J2000)

Observers should aim to reach signal to noise values of 50
or higher if possible. Transformed observations made in multiple
filters (at least Johnson B and V) may be useful for determining
the cause of variability if calibrated colors are obtained. If
submitting untransformed data, observers are encouraged to follow
this star as part of their long-term observing programs for at
least one season in order to allow researchers to determine
individual photometric offsets and combine data from multiple
observers.

Finder charts with a comparison star sequence for KIC 08462852 may
be created using the AAVSO Variable Star Plotter (VSP;
https://www.aavso.org/vsp).

Please report observations to the AAVSO International Database
using the name "KIC 08462852"; be sure to include the space between
"KIC" and "08462852". Note that the name KIC 8462852 is equivalent 
and may also be used.

following URL: http://arxiv.org/abs/1509.03622

Dr. Tabetha Boyajian (Yale University), lead author on the above
paper, has recently given a TED talk on this object; view it at:
