Historical observations
William Herschel (c.1784)

Published comments
Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads EL,BM,KNYPCHYPERIPH.
Sandage, A. et al. (1975) Galaxies and the Universe
G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the NGC 5676 Group are NGC 5676, NGC 5660, NGC 5633, NGC 5689 & IC 1029.

Burnham's Celestial Handbook
Burnham calls it a 11.9 mag spiral galaxy, measuring 3.0' x 1.5', which is bright, large, elongated and pretty gradually brighter in the middle.Mag 11 spiral galaxy in Bootes. Observers with large telescopes have mentioned a noticeable bright central region, described as a "particularly intense core" as seen in a 16-inch reflector.
Modern observations
Tom Lorenzin
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.9M; 3' x 1.5' extent; soft oblong with little brighter center; axis oriented NE-SW; bright star 20' to ESE is 5.5M SAO 45121; 25' ESE of SP GAL N5660; 50' to SSE is N5689."
Walter Scott Houston
Houston notes that this galaxy is the brighter of an interesting pair in Bootes. It measures 3'x1' and can be glimpsed with as little as a 4-inch aperture on good nights and is usually visible in a 10-inch, which will also reveal its companion, NGC 5660.
Ware, Donald J
"3' long by 1.5' wide with tapering ends, oriented NNE-SSW, and a broad concentration to the center."
(unknown)
This spiral galaxy lies three-quarters of a degree southeast of 24 Bootis and is of 11th mag. Its slightly oval disk is roughly 3' long. Between this galaxy and 24 Bootis lies the fainter NGC 5660.
Steve Coe
Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty large, much elongated 3X1 in PA 45 and brighter in the middle at 100X. Going to 165X will show off a stellar nucleus and some nice mottling on a sharp night."
