Strolling Astronomer p.63). Of great interest was a small dark

Similar objects have heralded major outbursts of activity in the
SEB in the past, but this one seemed to change little during the
period it was under observation (June 5 - August 14). Rotation
Periods. Only one observer, the writer, contributed transits
this year. When the 149 transits observed are plotted on graph
paper, 40 of them produce "drifts" for 12 Jovian marks. Because
