GCN Circular 18334

Dear colleagues,

This is a reminder to share the coordinates of the observations associated with G184098 within 12 hours of the observing time. To communicate
coordinates of EM observations, you can use circulars, the Electromagnetic Bulletin Board and GraceDB.


- Submitting a GCN Circular.

Several of you have asked how to send prose reports of observations and results on G184098. Because the private LIGO/Virgo GCN Circulars list is not
yet ready, for the time being please send reports to this list, lv-em-observers@gw-astronomy.org<mailto:lv-em-observers@gw-astronomy.org>. The subject
line should start with ��<80><9c>LIGO/Virgo G184098: ��<80><9c> and the body of the message should be in the format and style of an ordinary GCN Circular.

When the private GCN Circulars list is ready, we will re-ingest your messages so that they are archived and assigned circular numbers for citation
purposes.


- Submitting footprints of observations to GraceDB.

You can upload footprints of your observations into GraceDB manually in the ��<80><9c>EM Observations��<80><9d> section of the GraceDB event page
(https://gracedb.ligo.org/events/G184098), or in a scripted fashion using any of the following code samples:
