Comments:
1998:
Slowly fading (but still barely seen on Mar. 1.5)... end of outburst?
Relatively easy to see (again) on March 20, even shortly after Moonrise.
25.3 and 26.5 May 1998: the comet was marginally seen around m1 = 14, dia. 1' DC = 2, (169x256 L. Dilli. ). 26.3 July 1998: comet fainter than m1 = 14, nearby galaxy MCG 3-34-14, (5' East) was clearly visible (169x256 L. Dilli.).
