These observations indicate a rapid brightening and a possible
detection of the eclipse around 21h20m UT.

Observations are Pogson step estimates. Magnitudes are calculated
using the BAA sequence (visual magnitudes): E=10.10; F=10.37;
G=10.92; H=11.43; K=11.90.

Observer:
GRL = B. H. Granslo (Fjellhamar, Norway). Mostly clear, but
  cloud interference during Mar. 1.883-1.893 UT.

                                 Yours sincerely,
