TYC 0052-00796-1(mag10.0) by (45)Eugenia on 2011 Oct. 28 **** Successful observations: Observer: Xuejun Zhang (JOIN:13097) Place: Daqing, Heilongjiang, P.R.China Long.: 124o 51' 43.4" E, 46o 40' 51.6" N, Height: 148m (WGS84, MSL) Method: Visual, stopwatch, 20cm F4.5 Newtonian reflector Time signal: SW radio station BPM Result: D 14h 31m 57.27s +/-0.3s R 14h 32m 06.68s +/-0.3s Note: Observation was made from 14h 15m to 14h 40m. PE 0.3s applied. Telescope magnification 45.0. Clear and steady with some breeze. The asteroid was not visible. Geodetic coordinates were obtained by GoogleEarth. I found a suprising phenomenon in the process of this observation. The star got brighter to 8.5-magnitude in about two or three minutes before occultation start. This phenomenon lasted for about 2 seconds then the star recoverd to 10-magnitude. The star became dimmer obviously during the occulation but it still could be seen. This phenomenon lasted for about 9 seconds of time. Then the magnitude of the star recovered to 10th mag, and it has not changed its brightness after normal. ** Negative observations Observer: Hayato Watanabe (JOIN:13085) Place: Inabe, Mie, Japan Long.: 136o 33' 33.9" E, Lat.: 35o 07' 10.2" N, Height: 92m (JGD2000=WGS84) Method: VCR, 13cm F7.7 Refractor, WAT-120N(Slow shutter 4Fr) Time signal: GHS, TIVi
