The 4 S-NET (https://ilrs.cddis.eosdis.nasa.gov/missions/satellite_missions/current_missions/snt4_general.html (https://ilrs.cddis.eosdis.nasa.gov/missions/satellite_missions/current_missions/snt4_general.html)) satellites were launched on February 01, 2018. They have been difficult targets up to now. At Herstmonceux, we've had a number of unsuccessful attempts. And i think they have not been tracked by any station in the ILRS network.

However, next week (11th April) we expect to begin to see passes that are partially sunlit and so we will hopefully stand a better chance of getting some returns. This must also be true for other stations.
We will focus on S-NET4 as suggested in the recent ilrs-sta mail (https://lists.nasa.gov/pipermail/ilrs-sta/2018-April/005207.html (https://lists.nasa.gov/pipermail/ilrs-sta/2018-April/005207.html)).
Please use this space below to comment on your S-NET attempts, successes and failures over the coming weeks. Good luck!
