Report on behalf of GRANDMA collaboration.
We spatially cross-matched the LIGO/Virgo S240422ed event skymap (90% probability volume) with the mangrove [1] galaxy catalog and found 2244 compatible galaxies (see [1] for details). We ranked theses galaxies according to the grade presented in [1] which include the galaxies' stellar mass to characterize their probability for hosting the event.
The list of the top galaxies ranked using this grade has been shared for observation between the ASTEP telescope located at Concordia Station, LesMakes-T60 located at La Reunion, KAO in Egypte, TRT operated from Thailand and Kilonova-Catcher (KNC) telescopes. We started observations on 2024-04-23T09:49:17 (0.51 day after the GW trigger). Some of the observations were affected by the moon. We report in the following table the list of observed galaxies, as well as the achieved limiting magnitude (5 sigma, in AB, calibrated using the Skymapper and Gaia DR3 catalog) and the delay in hours between the gravitational-wave trigger and the observation. We observed a total of 47 galaxies. Some of the galaxies are reported more than once as they have been observed several times.
We also observed 14 NED galaxies provided in GCN 36243 with the Les Makes-T60 telescope located in La Reunion-France. We provide in the following table the list of observed NED galaxies, as well as the achieved limiting magnitude (5 sigma, in AB, calibrated using Pan-STARRS or GAIA catalog) and the delay in hours between the gravitational-wave trigger and the observation.

In our low latency analysis (Antier & Karpov, in prep), comparing to the Gaia catalog, we did not find any new candidates in our frames from LesMakes-T60 within the nearby the galaxies mentioned above.
In addition, we checked if counterpart candidates mentionned in previous GCN were in our images : Mag24a (discovered GCN 36267, discussed GCN 36270,32674,32675,32676,32680); AT2024hdl, AT2024hdm, AT2024hdn, AT2024hdo, AT2024hdp, AT2024hdq (discovered GCN 36273, AT2024hdl observed GCN 36297, AT2024hdm observed GCN 36279, AT2024hdn observed GCN 36280,36281, AT2024hdo observed GCN 36296; all observed GCN 36282 and discussed GCN 36283,36289); S240422ed_X101 (GCN 36278, observed GCN36282, 36287, 36293). None of these sources are located our fields.
We monitored S240422ed_X190 (GCN 32678) on MJD:60423.4324 in R and MJD:60424.4343 V band; we did not detect any optical counterpart. The depth of our images in Gaia DR3 is R: 19.7 (5 sigma, Vega) and V: 17.9 (5 sigma, Vega).
We also monitored S240422ed_X61 on MJD:60424.4209 in Ic band; we did not detect any optical counterpart. The depth of our images in Gaia DR3 is Ic: 17.6 (5 sigma, Vega).
We can provide at any time, any image from this campaign by request.
GRANDMA is a worldwide telescope network (grandma.ijclab.in2p3.fr) devoted to the observation of transients in the context of multi-messenger astrophysics [2]. Kilonova-Catcher (KNC) is the citizen science program of GRANDMA (kilonovacatcher.in2p3.fr).
