Variable star V515 And, Pieksämäki

I started the fall 2021 shooting season with the variable V515 And, which in one of the AAVSO observation campaigns https://www.aavso.org/aavso-alert-notice-753 was comfortably visible about 5 degrees above M31.
The V515 And is a white dwarf star of about 15 orders of magnitude that collects material from its companion - more information about the star: https://arxiv.org/pdf/1202.2493.pdf
I made a stack of measurements with regsitaxi with exposure 4h 15min.

There is one wandering 17.8 V-mag object in the stack, apparently an asteroid, I couldn't find a name for the object in Cartes - could someone dig the object's information from the image?

Location of the "asteroid":

2021-09-10 00:35:00 UT

Mean of the date RA: 00h57m 28.02s DE: + 46 ° 19 '20.8 "

Brightness measured 17.8 V-mag.

Observation site 62.26 N 27.11E

Huomasinkin havaintojasi AAVSOn tietokannassa.
Itsekin tehnyt tästä havaintoja, tosin vain 1/yö kun sitä pyydettiin.
En tiennyt että muutoksia tapahtuu näin lyhyessä aikamittakaavassa.

Asteroidi on (69701) 1998 HP49 JPL H 17.595mag. Mittauksesi on ihan hyvä 2mag ero johtuu varmaankin vertailutähdestä'.

Tarkoitin tietenkin 0.2mag eroa , 0 hävisi jonnekin. Erinomainen muuttujahavainto. ja plussana Mars-Crossing asteroidikin :).
