In response to our alert, Denis Buczynski and R.Moseley, Conder Brow Observatory checked the planet on July 18 at 02.40UT with a 0.15-m f/19 refractor at x150. They confirmed a major fading of the SEB at System 1 longitude 138d +-90d. Only a faint and attenuated belt was visible, probably the SEB(N). Further reports would be welcomed. P/COMET LOVAS 1 (1989p) T.Seki, Japan, has recovered this comet with a 0.60-m refl. on July 7 at m1=17.5. The correction for Delta(T) against MPC12135 is -0.22day. IAUC 4813 The comet is expected to reach mag 15 in Nov. Guy M Hurst
