Wang (THU) Report on behalf of the FRAM network, TAROT network and GRANDMA collaboration. We performed tiled observations of the LIGO/Virgo S191205ah event with the FRAM-Auger, TAROT-Calern (TCA) and TAROT-Chili (TCH) telescopes, operating in the R-band for FRAM and Clear for TAROT, located respectively at Pierre Auger Observatory (Malargue, Argentina), the Cote d'Azur Observatory and LaSilla ESO (LaS/ESO). The following table shows for each telescope: the delay in minutes from the trigger, which filter is used, the field of view of the telescope in degrees and the typical limiting magnitude (AB mag) for a given exposure in seconds (s). +-------------+---------+----------+-----------+------------+ | Telescope | Delay | Filter | f.o.v. | Limiting | | | [min] | | [deg] | Mag. |

to the time of the first and last exposure for a given tile. Observations are not necessarily continuous in this interval. The Probability refers to the 2D spatial probability of the GW skymap enclosed in a given tile. These observations cover about 4.8% of the cumulative probability of the BAYESTAR skymap created on 2019-12-05 21:53:08 (UTC). The coverage map is available at: https://grandma-owncloud.lal.in2p3.fr/index.php/s/XgtMhPRxcyL09gR/ download?path=%2F&files=GRANDMA_S191205ah_1575887414.png Tiles have been distributed to TAROT-Reunion(TRE) but due to communication issues, TRE did not observe producing a gap in the global coverage. The most probable region of the skymap was not observable due to moon constraints. No significant transient candidates were found during our low latency analysis [2,3]. GRANDMA (Global Rapid Advanced Network Devoted to the Multi-messenger Addicts) is a network of robotic telescopes connected all over the world with both photometry and spectrometry capabilities for Time-domain Astronomy [2](https://grandma.lal.in2p3.fr/). Details on the different telescopes are available on the GRANDMA web pages. [1] M. W Coughlin et al., MNRAS 2019, doi.org/10.1093/mnras/stz2485 [2] S.
