[neo_followup] Two CSS objects in particular need of follow-up

[Bill Gray]

Hello all,

    Catalina looks to have started out the lunation with a
bang.  Lots of 'C' designations on NEOCP right now,  and
several objects of particular interest.

    C2D5CK2 could really use some followup.  It's currently
at mag 18.9 and getting brighter as it approaches us (it's
about a million km away at present).  Unfortunately,  the
one-sigma ephemeris uncertainty is about ten arcminutes and
growing quickly.  Getting it in the next few hours would be
a Really Good Thing.  After that,  it'll take something with
a larger than usual field of view.  Perigee is in about ten
hours,  at roughly half the distance to the moon.

    C2D4Y62 isn't quite as urgent,  but could definitely use
some attention in the next 15 hours or so.  It's at mag 19.3,
and coming in to perigee at about 4:00 UT on the 18th.  Another
tracklet or two would enable us to follow it all the way in.
