Dear Observers,

Here is a new list of target.  There are not so many (demanding) targets 
on it, so I think that there may come time for adding targets in the 
categories 4 and 5 later in the lunation.  We'll see.

This list of targets is also available at

Clear Skies,

(1717)    Arlon             15.5  -18  155v  0.2  44  12.4 1.91 2.20  24opp
                  Return binary.
(2897)    Ole Romer         16.7   10  117v  0.2  62  13.2 2.02 2.25  19opp
                  Paired asteroid, P = 2.60 h, 3rd apparition; taking one
                  last lightcurve for this apparition would be useful
                  (errors <= 0.02 mag).

                  P = 3.63 h, 3rd apparition, one lightcurve per lunation 
                  sufficient.

                  Return binary, more data needed.

                  Return binary, more data needed.

1. NEOSource project targets:

                  Yarkovsky effect-detected asteroid.  Errors < 0.05 mag.

2. Returning binaries:
(6708)    Bobbievaile       16.1   -1  160   0.2  39  13.2 2.00 2.45  16opp
                  Return binary, 3rd apparition.
                  D_2/D_1 = 0.6, P_orb = 24.68 h, P_1 = 8.225 h

3. Paired asteroids (errors < 0.05 mag):
(7813)    Anderserikson     17.5   -5  162v  0.2  52  13.1 2.16 2.60  18opp

                  P = 4.92 h, 3rd apparition, errors < 0.03 mag needed.

4. Returning "prime suspects", to be followed up on their 2nd (3rd, ...) apparitions

5. New targets

Note: The ephemerides were computed for 2013-05-10
      ^/v means that the value increases/decreases by more than
      0.05 mag/day (for V) or by more than 0.5 deg/day for Dec and Elong.
      The rate of apparent motion (Mot) is in deg/day.
      Bga is the galactic latitude.
