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. |
|-------------+---------+----------+-----------+------------|
| FRAM-Auger | 490 | R | 1.0 x 1.0 | 18.0 (60s) |
| TCA | 1135 | Clear | 1.9 x 1.9 | 18.0 (60s) |
| TCH | 177 | Clear | 1.9 x 1.9 | 18.0 (60s) |
+-------------+---------+----------+-----------+------------+
We performed the following joint tiled observations [1] :

TStart and TEnd refer respectively 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/

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.
