8. ADDITIONAL COMMENTS

-Tangra software was used to produce the lightcurve.
-Occular Ver. 4.02 was used to evaluate the D and R times.
-A correction of -0.06s was performed because of the use of an integration camera.
-From the lightcurve it seems that the Disappearance was a bit slower than the Reappearance.
-A lightcurve can be seen here:
