Observations are not necessarily continuous\n ��in this interval.\nThe Probability refers to the 2D spatial\nprobability of the GW skymap enclosed in a given tile. Each tile is\n1.9x1.9 degrees. These observations cover about 27% of the cumulative\nprobability of the bayestar skymap with HLV.\nThe typical limiting magnitude is 18.0 for a 60.0 s exposure.\n\nThe coverage map is available at:\nhttps://grandma-owncloud.lal.in2p3.fr/index.php/s/7Y1Zos9G2n0rrrs\n\nNo serious transient candidates were found during our low latency\nanalysis.\n\nGRANDMA (Global Rapid Advanced Network Devoted to the Multi-messenger\nAddicts) is a network of robotic telescopes connected all over the\nworld with both photometry and spectrometry capabilities for Time-\ndomain Astronomy (https://grandma.lal.in2p3.fr/).\nDetails on the TCA telescope�� are available on the GRANDMA web pages\nor on�� http://tarot.obs-hp.fr/.\n\nThis circular is citable.",
