Hi,

The sky is very clear now. The 14.4 mag star in the same field is easily captured with a 4 second exposure on my StellaCam3.
After capturing some images of the dwarf nova BW Scl the previous hour, the equipment is now set for the occultation event.
The asteroid visually observe to move towards the star from NE direction.

WC Yue's prediction is excellent.
We visually observed the dimming of the star at almost exactly 17:41:00 UTC!
