I have noticed that LilacSat-2's FM transponder has been on nearly continuously for the past four days They may be keeping it active continuously during the holiday period in China.
It's worth checking out if you haven't worked it yet. It's got a good signal and can be easier to track than SO-50 because the carrier stays active for a period when not receiving signals. The downlink antenna also uses circular polarization, so there is less fading when using linear antennas than on SO-50.
Uplink: 144.350 MHz FM (No PL) Downlink: 437.200 MHz FM
Keep in mind that this uplink frequency is not within the normal 145.800 - 146.000 MHz satellite subband on two meters, though this frequency is within the 144.300 - 144.500 MHz "New OSCAR subband" in the ARRL band plan and is allocated to the Amateur Satellite Service (as is the entirety of 144 - 146 MHz). On passes over the United States, quite a few packet signals can be heard through the transponder.
If you use LoTW, the satellite name to use when uploading QSOs is 'CAS-3H.'
