Here we have the trail of NEO 2023 DZ2 as recorded on 23rd March 2023 from our back garden in Brisbane (Bortle 6-7). The Sky X Pro marked this NEO at Mag 16.4 at the time.
2023 DZ2 is an asteroid roughly 70 meters in diameter, classified as a near-Earth object of the Apollo group.
It was first observed on 27 February 2023, when it was 0.11 AU (16 million km) from Earth, with the Isaac Newton Telescope by Dr. Ovidiu Vaduvescu, Freya Barwell, and Kiran Jhass (ING and University of Sheffield student support astronomers) within the EURONEAR project.
It will pass 174,639 ± 27 km (108,516 ± 17 mi) of Earth on March 25, 2023. This is a little less than half the distance to the Moon.

Cloudy skies prevented the imaging of this object last night (Fri) at mag 15.4 and it looks like cloudy conditions will prevent me from tracking this NEO tonight (Sat) when it will make its closest pass at around mag 11.
If you have clear skies it would be worth getting out and observing this close pass.
Cheers
