Astrometry

the asteroid "Romania

Above is an animation (click on the image to view) showing the asteroid “Romania” moving slowly on the fixed star background.
The observation was part of the educational campaign Romania Observed From Romania.
The astrometric measurements were sent to the Minor Planet Center.


99942 Apophis:

Above is a 40 frames animation taken with the Atik 460ex on the RC8 (60 seconds integration each at bin2x2 with C filter) showing the movement of the Potentially Hazardous Asteroid (99942) Apophis during its March 2021 flyby (seen slightly left of the image center, with differential tracking on the asteroid). Observation time starts on the 3rd of March 2021 at 22:07 UT and ends at 22:47 UT on the same day.


NEO CONFIRMATIONS:


2019 YK4
See animation below:

The animation consist of 4 frames with 1 minute exposure each taken at 6 minute intervals between 2019-12-30 22:17:45 UT (beginning of exposure) and 2019-12-30 22:37:35 UT (end of exposure).
Equipment used: RC8 with Atik 460ex bin2x2 – clear filter (with this setup 17th magnitude objects can be easily detected with only 1 minute integration in decent sky conditions when pointing near zenith).
Precision astrometry made using Astrometrica software and reported to the Minor Planet Center ( see MPEC 2019-Y131 : 2019 YK4 )


2020 WP4

This is an 18 frame animation from the first batch of images with 2.5 minute exposure each taken sequentially between 2020-11-24 21:09:39 UT (beginning of exposure) and 2020-11-24 21:52:38 UT (end of exposure).
Equipment used: RC8 with Atik 460ex bin3x3 – clear filter (the 19th magnitude asteroid was detected with 2.5 minute integration time and differential tracking/guiding under a moonlit sky).
Precision astrometry made using Astrometrica software and reported to the Minor Planet Center ( see MPEC 2020-W155 : 2020 WP4 )
