Sunspots Sketches
April 25th to May 2nd, 2000
 


      
April 25th                             April 29th                           May 2nd

The above sketches were made during a period of high sunspot activity during the last week of April 2000.  The two major spots, seen just leaving the sun on May 2nd were visible without a telescope (with the appropriate filter over the eyes, of course).
Sketches were made looking through a Meade 90mm ETX, with a Thousand Oaks Polymer Plus solar filter.  A light green filter on the eyepiece was used to enhance the visibility of grain and facula.  In order to get a un-biased sketch, each day's sketches were made without looking at the last sun sketch.
