    The Af rho quantity showed a progressively rising ascending branch, followed by an apparent flat maximum that lasted for 2 months, from about -10 to +50 days from perihelion. In this period, Af rho peaked at around 100 cm in R band with strong short term fluctuations between 70 and 140 cm. Early signs of activity were detectable well before perihelion (about 80-90 days before) and a random variability is also present in the descending branch after perihelion. Three post perihelion data points (between +55 and +61 days) from the 1997-1998 apparition show a bit higher Af rho value of our observation and a similar fast variation.
