All but two were observed with a Johnson V filter. The first event was observed with a B filter, and the second event was observed with a Gunn R filter. The 1985, 1986, and 1987 events used a Texas Instruments 320x520 CCD, while the 1988 and 1990 events used a Texas Instruments 800x800 CCD, both mounted on the 60-inch telescope at Palomar. Calibrated magnitudes were not reported. The magnitudes given in this data set are differential with respect to the pre- or post- event magnitude as defined by a group of points identified in the reference. That same table in the reference also lists the total number of points obtained on each night, but there are discrepancies between the number of points listed in the table and the number of values published. The following list shows the published and corrected number of points: UT Date published actual ------------- --------- ------ 1986 March 04 112 109 1986 April 05 119 118 1986 June 08 49 44 1986 June 27 61 48 1988 March 14 74 73 1988 March 17 123 116 1988 May 17 127 103 1988 June 05 164 144 Buratti, B.
