Dear fellow astronomers
It is with great delight that I can officially report a new Binary Star discovery found in the constellation of Perseus (Star identifier: GSC 02875-02470) by Irish and Italian astronomers working in collaboration.
The discovery was serendipitously made while the team were undertaking photometric observations of main belt asteroid (69315) 1992 UR2 with a diameter of some 4.5 km, to determine its rotation period which turned out to be a very slow rotator indeed at some 106 hours, considering most minor planets studied so far in this manner (some 5,500) have rotation periods of between 4 and 10 hours.
See Link: adsabs.harvard.edu/abs/2018MPBu...45..167F for more in depth observations and analysis of this asteroid by the team.
The initial discovery was made from Cherryvalley Observatory (I83) Co. Meath Ireland and the Italian team were alerted for follow up observations which were carried out from both Italy and Ireland. I am very proud to be part of this discovery team and wish to thank my Italian friends for their hard work and their time in carrying out both the follow up observations and in depth analysis, in particular Mr. Fabio Salvaggio whom is very skilled and knowledgeable in this area, truly a team effort and a great result working in friendly collaboration.
For details on this discovery, now designated 000-BMX-685 please follow this AAVSO link to The International Variable Star Index Website for more info: www.aavso.org/vsx/index.php…
The binary system is of type EA (β Persei-type (Algol) eclipsing system with a period of just over nine days.

Superb work Mike! Well done!
It's a testament to the effort you have put in over countless nights and shows the benefits of working as part of a team, where detailed analysis and follow-up observations can be made.
A night Christmas present! Many congrats to you and your Italian colleagues.
