report on behalf of the FRAM network, TAROT network
and GRANDMA collaborations:
We performed tiled observations of the LIGO/Virgo S191105e event with
the FRAM-Auger (FRAM-A), FRAM-CTA-N (FRAM-C), TAROT-Reunion (TRE),
TAROT-Calern (TCA) and TAROT-Chili (TCH) telescopes operating
in the r-band and visible located respectively at
Pierre Auger observatory (Malargue, Argentina), Roque de los Muchachos
observatory (La Palma, Spain), Les Makes astronomical
observatory, the Cote d'Azur observatory and La Silla ESO
observatory (LaS/ESO).
The observation started on 11/08/19 00:10:14 UTC for FRAM-Auger which
corresponds approximately to 3456 minutes after the GW trigger time.
The observation started on 11/08/19 01:17:32 UTC for FRAM-CTA-N which
corresponds approximately to 3523 minutes after the GW trigger time.
The observation started on 11/07/19 15:32:23 UTC for TRE which
corresponds approximately to 2938 minutes after the GW trigger time.
For TCA it started on 11/07/19 22:37:51 UTC which corresponds
approximately to 3363 minutes after the GW trigger time.
For TCH it started on 11/07/19 23:55:24 UTC which corresponds
approximately to 3441 minutes after the GW trigger time.
We performed the following joint tiled observations [1]:

TStart and TEnd refers 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.
Each FRAM-Auger tile is 1.0x1.0 degrees and 0.45x0.45 degrees for
FRAM-CTA-N.
Each TRE tile is 4.2x4.2 degrees and 1.9x1.9 degrees for TCA and TCH.
These observations cover about 40% of the cumulative probability of the
Bayestar skymap available on Nov 6, 2019 18:01:59 UTC.
The typical limiting magnitude in R (AB mode) is 16.0 and 18.0 for a
120 s exposure for FRAM-CTA-N and FRAM-Auger, respectively.
The typical limiting magnitude in AB mode is 17.0 and 18.0
for a 60.0 s exposure for TRE and TCA/TCH, respectively.
The coverage map is available at:

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].
