OCCULTATION OF PPM 709119 BY 314 (ROSALIA)
Further to the prediction on E1232, Gary Poyner, Birmingham,
England e-mails:
Negative observation.                           52,32,32N  1,52,30W
Rosalia's magnitude estimated at 13.7 using GSC values.
September 12/13 1997 Start:  23h 50m UT End:    00h 10m UT
Telescope Type:  Newtonian f5 Aperture:  40cm Mag. x118
Mount:  Alt-Az. Motor Drive: No
Mode of time recording:  Digital watch
Atmosphere Transparency:  Very transparent
Star image stability:  4 (Ant) Wind Speed:  Calm Temp: 7oC

Richard Miles reports:
No positive observation of the September 12/13 event involving 314
Rosalia has been reported to the author.  Three negative
observations have been reported by:

Hazel McGee, Clandon, Surrey, UK (51 16 N, 00 30 W )
Terry Platt, Binfield, Berkshire, UK (51 25.5 N, 00 47.4 W, Height
45 m)
Gary Poyner, Birmingham, UK (52 32.53 N, 01 52.5 W ).

Several observers (including Alan Bowden, Geoff Kirby, myself and
probably many others too) were 'rained off' shortly before the
predicted time.

Although last-minute astrometry was provided by two sources, Jim
Roe in Montana, US, and Angel Lopez in Mallorca, Spain, the
reductions were not posted up until an hour or so before the
actual event by both Jan Manek and David Dunham.  This astrometry
indicated that the path had shifted significantly south passing
over Sardinia, central Italy near Rome and part of the Ukraine.
A plot of the 'last-minute' prediction from Jan Manek is available

OCCULTATION OF GSC 1228 0174 BY 37 (FIDES)
Richard Miles provides predictions for two further events:
37 FIDES on September 16/17 (Observable photoelectrically)
This 112 km diameter object is predicted to occult the star,
GSC 1228 0174 (V=11.6 approx.) located at:
RA(2000): 3h 09m 28s  Dec(2000) +19deg 22'43"
at 22:27-22:55 UT, mid-time (from the UK) = 22:41 UT
The maximum duration of the event: about 30 seconds.
The star may dip in brightness by only about 0.4 magnitudes.
The asteroid should be readily visible at around V=10.9, diameter
0.100".

OCCULTATION OF PPM 94351 BY 27 (EUTERPE)
27 EUTERPE on September 17/18 (Observable visually)
This 119 km diameter object is predicted to occult the star,
PPM 94351 = GSC 1308 1492 = SAO 77160 (V=9.7 approx.) located at:
RA(2000): 5h 25m 31s
Dec(2000) +21deg 55'07"
at 00:15-00:26 UT, mid-time (from the UK) = 00:21 UT
The maximum duration of the event: about 6.5 seconds.
The star may dip in brightness by about 1.5 magnitudes.
The asteroid should be readily visible at around V=11.0, diameter
0.097".
