    Late on Apr 21 UTC, after your observations, the official designations were changed. What was originally called D is now
    A (Resourcesat 2), for which it appears that official TLEs will not be published. The original A became B (Youthsat);
    the original B became C (Xsat), and the original C became D (rocket body). So you observed Resourcesat 2, preceded by
    the rocket body. The other two satellites are small, so will be difficult to see in binoculars, if at all.
