**Station Maps for the Occultation by (22) Kalliope and its Satellite Linus at Tuesday, 2011 November 22 (~ 02:39 UT)
**

Magnitude of target star 2UCAC 42217550 : 10.8 mag

UCAC instrumental “pseudo-R” fit-model magnitude: 10.8 mag (data from UCAC3)

**(22) Kalliope:**

The max duration is expected to be 25.4 sec with a max drop of 0.7 mag.

The event will take place at an altitude of 69 deg and at azimuth 212 deg. The sun will be at an altitude of -39 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of ± 0.27 path widths.

The probabilities to see a positive event:

Centre line: ~ 88 %

Path limits: ~ 50 %

1 sigma lines: ~ 16 %

2 sigma lines: ~ 2 %

**Linus:**

The max duration is expected to be 4.3 sec with a max drop of 0.6 mag.

The event will take place at an altitude of 73 deg and at azimuth 189 deg. The sun will be at an altitude of -45 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of ± 2.11 path widths.

The probabilities to see a positive event:

Centre line: ~ 19 %

Path limits: ~ 18 %

1 sigma lines: ~ 9 %

2 sigma lines: ~ 1 %

(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)
