Description:
The next observation in my Virgo Cluster Barnstorm tonight
(see previous logs) was more of a visual challenge. I began
with 27 Virginis, a bright, pretty, uneven pair (7,10;290o)
which forms the N arm of the quadruple around rho Vir. The
comes (fainter member) of 27 points the way 20' W to a mag.
12 star. Keeping 27 out of my field of view to avoid glare,
i3647 was only JUST visible to averted vision at high power
(210x). No details at all were noted in this (LSB?) dwarf.
