With NPOE integration of elsets 130.54-131.16, the decay occurs on May 13, around 16:00 UT. I wish I had found time to make this exercise when the elsets appeared !

Monday's last elset (Element set number = 2) shows a very small ndot, and a MM which also seems to small. The preceding elset (Element set number = 4) has an MM which may be too small. Integrating from the third elset (Element set number = 1) I get decay at May 13 23:23 UT ! Good luck, and report your observations !
