The mag 18.6 asteroid (19810) Partridge, 9 km in diameter, was predicted to occult a mag 12.1 Kepler2 star in Leo on 2019 April 12. Observers within the 12 km wide shadow track could see a brief drop in brightness of 6 magnitudes for up to 1s.

My site was 51 km outside the predicted track with a 3.9% probability of success. I was delighted to record a dip in brightness of 0.96s as the asteroid occulted the star. The attached plot shows the analysis of the light curve using Tangra and AOTA.

    D  - 22 07 16.83 ± 0.04

    R  - 22 07 17.79 ± 0.04

I must have been very close to the centre line of the asteroid's shadow. The mid-time of the occultation and the Gaia position of the target star will give high-precision astrometry of the asteroid. 

Compensation for having missed some recent high probability events due to cloudy nights.
