  ASTEROID : (275) SAPIENTIA

2.OBSERVER:
 Name: Stefano SPOSETTI
 Address: CH-6525 Gnosca, Switzerland
 E-mail: spo@bluewin.ch

3.OBSERVING STATION:
 Nearest city: CH-6500 Bellinzona
 Station: Gnosca Observatory
 Latitude: 46deg 13min 54sec (N)
 Longitude: 9deg 1min 30sec (E)
 Altitude: 260 m
 Single/Multiple: single

4.TIMING OF EVENTS:
 Occultation recorded: NO

5.TELESCOPE:
 Type: Newtonian
 Aperture: 40cm
 Magnification: -
 Mount: equatorial
 Motor drive: no

6.TIMING & RECORDING:
 Timekeeping: telephone speaking clock
 Mode of recording: CCD scan
 Device of recording: CCD

7.OBSERVING CONDITIONS:
 Atmospheric transparency: good
 Wind: no
 Star image stability: good
 Temperature: 0 deg C

8.ADDITIONAL COMMENTS:
Due to CCD "drift scan" mode I observed no occultation in seven 70-seconds
intervals.
U.T. intervals :
from 23:51:22  to 23:52:32
from 23:52:42  to 23:53:52
from 23:54:02  to 23:55:12
from 23:55:23  to 23:56:33
from 23:56:43  to 23:57:53
from 23:58:03  to 23:59:13
from 23:59:23  to 00:00:33
Precision of time measurement: +-1sec.

My location was about 50km north of the northern limit of the path given in the
Jan Manek update, so I am not surprised nore disappointed for my negative
result. I think, in opposite, that my negative measure constrain the effective
ground path.

Sincerely,
S. Sposetti
