First the time given was local Summer time, so 19:26:56.3 UT is the proper time.

On Apr.19 I observed it 59 sec. early wrt. this improved elset, on a near
zenithal pass, so the suggestion to change B*/ndot2 instead of MM seems
appropriate:
19:31:26.4 RA 11.11 dec.+56.5 (2000)
19:31:32.8    10.95      61.6
19:32:14.0     4.49      83.7

About mag. +2 for two long periods.
