I was not even aware of this group (and I live in Israel...). Some digging brought the jackpot: [The Israeli New Moon Society](https://sites.google.com/site/moonsoc/). Here's what they have to say on the matter: >On 7th May 2008 the Sanhedrin reenacted a reconstruction of receiving eyewitness testimony of the crescent Moon used for fixing the calendar and have carried out many such reconstructions since. This has helped improve the efficiency and accuracy of the process. ![First reconstruction of receiving testimony about the crescent Moon in Jerusalem](https://judaism.codidact.com/uploads/8ZqCzhBHHcz3r4VTG1tiC7gb) >On 6th January 2011 members of the Sanhedrin went up to the Temple Mount, received eyewitness testimony about the Moon, sanctified the month and announced “mekudash mekudash”. This was a forbidden act that will probably bring about an end to this Sanhedrin. ![Sanctification of the month on the Temple Mount](https://judaism.codidact.com/uploads/pqhiGf8VMZojfgFkEXU31jHK) Here's a [Hebrew article](https://www.ynet.co.il/articles/0,7340,L-3541740,00.html) on the subject. And a [listing ](http://www.thesanhedrin.org/en/index.php/Committee_concerning_the_fixing_of_the_Calendar)of their moon reports until 2009. A [listing ](https://sites.google.com/site/moonsoc/news) of moon reports until 2011. The latest piece I could find is from the New Moon Society which is from way back in 2011, so I don't know what they're doing nowadays.
