Lunar Orbiter IV-143-h3
This overhead view is centered on the ruined 112-km diameter ring of Flamsteed P.
Flamsteed itself is the pronounced crater just inside the southern end of this ring. To its southeast is 10-km Flamsteed B, and on the floor of the ruined ring are 6-km Flamsteed D and 4-km Flamsteed K.
The individual arc-shaped sections of the large Flamsteed P ring were once known as Flamsteed Gamma (west of Flamsteed), Flamsteed Delta (northwest of Flamsteed), Flamsteed Psi (north-northwest of Flamsteed), Flamsteed Phi (north-northeast of Flamsteed), Flamsteed Beta (northeast of Flamsteed), and Flamsteed Lambda (east of Flamsteed), see chart SLC F5 (system of Lunar Craters, 1966).

Rough looking craterlet with surrounding field of boulders

At the northern part of the Flamsteed P ring (2°20' South/ 43°55' West), an unnamed rough looking craterlet with surrounding field of boulders was captured on Lunar Orbiter 3 frame LO3-189-h2.
  A section of this photograph (close-up of the rough looking craterlet) was printed in the book Geology on the Moon (J.E.Guest/ R.Greeley). In the German edition of this book (Geology auf dem Mond), this photograph was printed on page 136.
  The high-albedo ejectablanket around this craterlet, appearing as a bright dot or "point", is seen on page 150 (LAC 75) in the Clementine Atlas of the Moon (Bussey/ Spudis) at the above mentioned coordinates. In other words: it is observable through common telescopes; before, during, and after Full Moon.
  It is also detectable on chart 26 (page 65) in the 21st Century Atlas of the Moon (Wood/ Collins), at location H-1/2 (the northern part of Flamsteed P's floor).
  See also the purple "blob" in the USGS's Geologic map of the Flamsteed K region (I-626).

Description

Flamsteed is a small complex crater with rim slumps, especially on the southern edge where a scallop marks where wall material slid into the crater. A large ruined crater, Flamsteed P, extends to the north of Flamsteed. This 112 km diameter partial ring was a normal crater that has been nearly completely covered by [/Oceanus%20Procellarum Oceanus Procellarum] lava flows. - tychocrater tychocrater Sep 29, 2007

([/IAU%20Directions IAU Directions]) FLAMSTEED.--A bright ring-plain, 9 miles in diameter, in a barren region in the [/Oceanus%20Procellarum Oceanus Procellarum], N.W. of [/Wichmann Wichmann]. It has a regular border (broken at one place on the N. by a gap, which probably represents a crater), rising to a height of about 1,400 feet above the surrounding plain. A great enclosure, 60 miles in diameter, lies on the N. of Flamsteed. It is defined by low ridges which exhibit many breaks, though under a high light the ring is apparently continuous. Within are several small craters and two considerable hills, nearly central.

Quite large circle-shaped formation southwest of the Flamsteed P ring

What seems to be a circle-shaped formation southwest of the Flamsteed P ring is an arrangement of wrinkle ridges, more-or-less... well... circle shaped (see SLC-map F5). Is it perhaps part of the remains of the Flamsteed-Billy impact basin? - DannyCaes DannyCaes Feb 4, 2017
 
 

Nomenclature

• Named for John Flamsteed (19 August 1646 - 31 December 1719), an English astronomer. On 4 March 1675 he was appointed by royal warrant "The King's Astronomical Observator" — the first British Astronomer Royal, with an allowance of £100 a year.
• According to [/Whitaker Whitaker] (p. 219), this name was introduced by [/M%C3%A4dler Mädler]. The names Flamstedius and Flamsteedius had been used earlier by John Keill and by Maximilian Hell, but for different formations (pp. 89, 93-94).
• Printed as Flamstead on top of the nomenclature gazetteer near the right margin of the National Geographic Society's revised and reprinted edition of the map THE EARTH'S MOON. - DannyCaes DannyCaes Oct 7, 2015 (this map is a nitpicker's delight!).
• Crater Flamsteed K (on the floor of the Flamsteed P ring) is called Flamsteed D on chart 51 in the Times Atlas of the Moon. - DannyCaes DannyCaes Mar 17, 2014
• Crater Flamsteed D (also on the floor of the Flamsteed P ring) is called Flamsteed E on chart 51 in the Times Atlas. - DannyCaes DannyCaes Mar 18, 2014
• In selenography, craters Flamsteed D and K (both in the Flamsteed P ring) seem to be quite a confusing pair, because on LAC 75 (page 151) in the 2012 edition of the Clementine Atlas of the Moon (Bussey/ Spudis), Flamsteed D was printed at the location of Flamsteed K, and Flamsteed K at the location of Flamsteed D.- DannyCaes DannyCaes Mar 18, 2014
• In the 2004 edition of the Clementine Atlas, Flamsteed D was "Flamsteed E", and Flamsteed K was "Flamsteed D".- DannyCaes DannyCaes Mar 19, 2014
• Flamsteed P is called the Flamsteed Ring on Chart 26 (page 65) of the 21st Century Atlas of the Moon (Charles A. Wood/ Maurice J.S. Collins).
