ITF-2 is now Tsukuba-OSCAR 89 or TO-89 per Bill Tynan, W3XO, OSCAR Number Administrator

CAS-4A/OVS-1A and CAS-4B/OVS-1B where launched today (06-15-2017) at 03:00 GMT from the Jiuquan Satellite Launch Center of China using a CZ-4B launch vehicle See amsat-bb email below from Alan Kung, BA1DU Nico Janssen, PA0DLO notes that these two new satellites are two of the four NORAD ID CAT 42578-42761 For now the 06-15-2017 AMSAT-NA KEP Distribution list them as follows:

Name NORAD CAT ID Object A 42758 Object B 42759 Object C 42760 Object D 42761

More later as these objects separate and are identified
