COMET C/2013 E2 (IWAMOTO)
Ernesto Guido et. al. report that they performed follow-up measurements 
of this comet (see TA E-Circular 2901) remotely using the iTelescope 
network (Siding Spring MPC 062) on 2013 March 14.8 through a 0.50-m 
f/6.8 astrograph + CCD + f/4.5 focal reducer.

The image of a stack of 5x20-second exposures was obtained a few minutes 
before sunrise with the sun only 10 degrees below the horizon and the 
comet +27 degrees above the horizon.

A further image of March 15.5UT was obtained and can be found at:
