From October 2014 until now (about 10 years) we did the astronomical observations of the Gaia Alerts or Gaia Fellow Up Network for Transients Objects (Gaia-FUN-TO). At 2013 we organized our local cooperation “Serbian-Bulgarian mini-network telescopes” to get better results. Also, the mentioned observations and investigations are in line with actual joint research SANU-BAN project “Gaia astrometry and fast variable astronomical objects” from 2023 to 2025; SANU-BAN are Serbian and Bulgarian Academies of Sciences. Now, there are 8 astronomical instruments at two sites in Bulgaria (at Belogradchik and Rozhen) and one site in Serbia (Astronomical Station Vidojevica - ASV). Usually, we did about 15 Gaia Alerts objects per year. During 2023, we did 12 Gaia Alerts: Gaia22ang (5 times), Gaia22dze, Gaia23bay (6), Gaia19dmj (2), Gaia21cgt (2), Gaia22eem (2), Gaia23afy, Gaia23cer (2), Gaia23cri (3), Gaia20cwd, Gaia23bbk and Gaia23cvq; about 300 CCD images were done using the 60 cm and1.4 m ASV telescopes. We present some results, here.
