Visibility II / V
There has been a few times practiced making light curves for changing stars and now it was time for a slightly more difficult challenge, that is, the exoplanet overflow light curve.
Suitably, in the last sufficiently dark nights, the easiest way for the exoplanet to be covered in the constellation of Virgo happened.
That exoplanet is called Qatar-2b and its brightness is mag 13 and during the passage the brightness dims to about 0.03 magnitude. The blackout lasts 108 minutes.
The light curve became reasonably good, although in the final stage the weather deteriorated quite significantly.
In the upper image, the star's brightness curve that tells us when the exoplanet is in front of its parent star when viewed from us.
The lower image in the middle shows the star to be photographed and the upper left shows the reference star with its brightness reading.
According to current knowledge, this star also has two planetary orbits.
