Occultation of TYC 5303 00317 by (194) Prokne - 1999 November 2:
1½ hours before the Prokne occultation it was still 100% thick overcast clouds as it had been all evening so I opted for my beauty sleep.
I monitored the Prokne appulse last night, and saw both star and asteroid.The images merged at about 11:58 UT. At about 12:14 I thought I saw them resolved again during fleeting moments of clarity, and they had definitely separated by 12:15.
