Subject: Crater size sequence chart for the central north Oceanus Procellarum


This is to announce a webpage that contains a crater size sequence
chart for the central north Oceanus Procellarum region. The crater
size chart generally covers the area bounded by Reiner Gamma to
Aristarchus to Kepler to Flamsteed and N24, W65 to N24W35 to S5,W35 to
S5, W65. Almost all craters less then 20 km in size, ranging from 1km
to 18km, are charted. Approx. 110 satellite craters are plotted. The
chart can be found at:

http://members.csolutions.net/fisherka/astronote/plan/trl/cscW55N0.html

This crater sequence chart is intended as a resouce for amateur
astronomers to explore crater sizes that are visible at various
magnifications and apertures. By comparing the annotated Clementine
sinusodial projection base map with charts in R=FCkl's Atlas, one also
can gain an appreciation of that selenographic latitude and longitude
has on foreshortening the appearance of craters.

An Excel catalogue of approximately 2630 near-side craters of less than
20km in size is provided for download. By using Microsoft Excel's data
filter feature, users can quickly develop a list of small craters on
any R=FCkl chart. Sample worksheets used to develop the central north
Oceanus Procellarum crater sequence chart displayed here are included
in the Excel spreadsheet.
