  "body": "James Freeburn (Swinburne/OzGrav), Jonathan Carney (UNC), Igor Andreoni (UNC), David Cook (IPAC):\n\n\nWe followed up the gravitational wave trigger S250206dm (GCN 39175, GCN 39178, GCN 39184) using the Goodman High Throughput Spectrograph mounted on the SOAR telescope in imaging mode via Target of Opportunity observations (PI Andreoni). We observed 33 galaxies in the highest probability region (Cook at al. GCN 39174, GCN 39177, GCN 39185) using the list produced by crossmatching the sky localization with the NED Local Volume Sample (NED-LVS; Cook et al. 2023). Specifically, we considered the galaxy list obtained using the LVK S250206dm-6-Update sky localization (Cook at al. GCN 39185), focusing on the Southern high probability area.\n\nObservations were acquired from 2025-02-07 06:18 UT until 08:48 UT. Each galaxy was observed with 60s exposures in g+i filters. A list of the observed galaxies is presented in the table below. The completed pointings were uploaded to TreasureMap: https://treasuremap.space/alerts?graceids=S250206dm\n\nData analysis is ongoing.\n\n\nobject_name\tcoordinates\nWISEA J161708.84-674024.7\t16:17:08.87 -67:40:22.49\nWISEA J162759.57-693615.7\t16:27:59.57 -69:36:15.71\nWISEA J154439.56-665529.0\t15:44:39.56 -66:55:29.08\nWISEA J155633.83-693531.5\t15:56:33.83 -69:35:31.55\nWISEA J160843.41-685023.4\t16:08:43.41 -68:50:23.44\nWISEA J154441.36-665502.6\t15:44:41.37 -66:55:02.61\nWISEA J160915.94-690504.9\t16:09:15.95 -69:05:04.94\nWISEA J161332.77-674621.1\t16:13:32.78 -67:46:21.13\nWISEA J165614.58-695645.9\t16:56:14.58 -69:56:46.00\nWISEA J163330.53-670950.7\t16:33:30.54 -67:09:50.72\nWISEA J154538.24-703944.1\t15:45:38.25 -70:39:44.12\nWISEA J153057.77-694546.5\t15:30:57.77 -69:45:46.58\nWISEA J160838.27-700230.8\t16:08:38.27 -70:02:30.85\nWISEA J111435.41-485220.0\t11:14:35.41 -48:52:20.02\nWISEA J161213.79-710729.1\t16:12:13.79 -71:07:29.14\nESO 069-IG 006N\t            16:38:11.94 -68:26:08.84\nWISEA J165744.21-680430.9\t16:57:44.21 -68:04:30.93\nWISEA J165527.54-702337.9\t16:55:27.54 -70:23:37.91\nWISEA J110452.75-455440.5\t11:04:52.76 -45:54:40.57\nWISEA J163202.83-693109.0\t16:32:02.84 -69:31:09.01\nWISEA J164922.44-690054.7\t16:49:22.44 -69:00:54.76\nWISEA J161735.32-701416.0\t16:17:35.32 -70:14:16.00\nWISEA J163253.56-702946.2\t16:32:53.57 -70:29:46.22\nWISEA J164915.17-690004.8\t16:49:15.17 -69:00:04.87\nESO 069- G 003\t            16:24:32.07 -68:49:12.91\nWISEA J161946.23-690837.2\t16:19:46.23 -69:08:37.26\nWISEA J153854.81-680647.5\t15:38:54.81 -68:06:47.55\nWISEA J151821.27-691417.9\t15:18:21.28 -69:14:17.93\nWISEA J155653.84-695749.1\t15:56:53.88 -69:57:49.18\nWISEA J165438.30-670413.8\t16:54:38.30 -67:04:13.82\nWISEA J163224.97-700239.7\t16:32:24.97 -70:02:39.78\nWISEA J110509.11-450337.3\t11:05:09.11 -45:03:37.38\nWISEA J161822.73-683741.1\t16:18:22.73 -68:37:41.20\n\n\nWe thank the NOIRLab and SOAR staff for their excellent support.",
