(34339) 2000 QH218 Occults Naked-Eye-Star on 2019 February 05 in Europe

In the late evening of February 5th, the 11-km minor planet (34339) 2000 QH218 will occult HIP 48455 (3.4 Vmag). Observers in the occultation path will see a disapperance of the most northern star in the lion’s head in the constellation Leo for an expected duration of 1.4 sec.

In Europe the centre line will cross Ukranie and Moldavia (~22.20 U.T.), Romania and Hungary (~22:21 U.T.), Austria [~22:22 U.T.) and Switzerland and France (~22:23 U.T.). In the case of an occultation by the minor planet the combined magnitude will drop about 14.1 mag. The target area is located about 61 deg above the horizon in the southeastern sky (for position at centre line at E 12 deg).

Observers with video or CCD cameras should be aware that fading of the light of the target star is possible due to the star diameter. A high frame rate is requested for recording this phenomena. Please choose the exposure carefully and avoid any saturation of the target star.
