About 3000 Gaia Alerts were done by the Gaia Science Alerts group during the last three years (period October 2014 - October 2017). We have observed about 45 objects (near 1650 CCD images) of Gaia-FUN-TO for that period; it is about 15 objects (near 550 CCD images) per year. The standard Jhonson BV and Cousins RI filters were used, and bias, dark and flat-fielded corrections were applied (plus hot/dead pixels, shutter effect, etc.). The astrometry solution for individual data frames was done in Astrometry.Net (http://astrometry.net), and the Source Extractor was used for the aperture photometry measurements. Finally, the data were sent to the Cambridge Photometric Calibration Server (CPCS) for further callibration (http://www.ast.cam.ac.uk/ioa/wikis/gsawgwiki/index.php/Follow-up). At the end of 2014, the rare object Gaia14aae (GaiaVerif14acp), the deeply eclipsing AM CVn system, was actual and we did our efforts to observe it; as a result, the paper about it (Campbell et al. 2015) was published. In the last two years, another rare object, Gaia16aye - the binary microlensing event, was very interesting and we observed it many times. Also, other rare Objects (supernovae, cataclysmic variables, etc.) were observed. To do that, we have used 6 instruments via local cooperation "the Serbian-Bulgarian mini-network telescopes" (established in 2013) and SANU-BAN joint research project "Study of ICRF radio-sources and fast variable astronomical objects" for three-years period (2017-2019, the head is G. Damljanovic). In the last two years, the 60 cm Rozhen telescope (Bulgaria) has been under reconstruction, but there is a new one, the 1.4 m ASV (Serbia) from mid-2016 via Belissima project. The first data of the 1.4 m ASV are very good. Some results about the Gaia- FUN-TO are presented, here.
