The Total Lunar Eclipse of 16 July 2000

by Peter Anderson

Because the photos were at the F6 prime focus of my 16" (41cm) Newtonian reflector, the moon was barely accommodated in the height of the 35mm frame, and so one edge of the frame needed extending and filling in for aesthetic purposes. After converting and saving the images, I noticed that this is a little lighter than intended in several of the finished images.

Apart the above, spot removal, and small adjustments in brightness and contrast, no other adjustment has been made to the images which were scanned from 10cm X 15cm prints from the Kodak 100ASA colour print negatives. Processing of the film was by Kodak. For the purpose of reducing the size of the files for this web page, the scanned images of each print was reduced to 120dpi and saved at 50% using the 'U Lead Photo Express 2.0 SE' program. (If anyone is performing any detailed investigation I can Email the original images scanned at 300dpi and saved at 85%)

These six photos represent six quick ‘photo breaks’ which were taken during the course of the eclipse. These were quite incidental to the main work I was doing. I was very busy throughout, making a total of 71 crater shadow timings, timing 17 occultations (all but 5 of unidentified stars as faint as estimated mv.11.5 ) and doing three quick TLP sweeps at 13hrs 05min, 13hrs 50min, and 14hrs 50min. (nothing specifically anomalous) During totality, I checked the southern horizon a number of times for auroral activity, just in case the burst of solar activity of the previous few days had given rise to anything. Following the eclipse I monitored a star which was predicted to be occulted by the asteroid 235 Carolina a little after 3am. After all this, I was very tired!

My impression was that the eclipse was fairly dark and not as coppery as in previous years when there was considerable volcanic dust in the atmosphere. Perhaps it was the low level of illumination which gave the impression of the muted colour. Certainly it only appeared a dull copper with some grey. The photographs bring out more colour. It must nevertheless be remembered that the moon passed virtually centrally through the shadow of the earth and so one would expect it to be darker at mid-eclipse. My impression that it was quite dark is subjective; I did not make any measurements.

I also had the impression that the Earth’s shadow during the partial stages was not as distinct. However this may simply have been that I was using a wide angle 12.4mm eyepiece at X198 throughout. Had I been using a lower magnification, I may well have had a different impression.

The eclipse was virtually overhead here in Brisbane (27° 30’S, 153° 00’E). The weather was clear, mild, and still – perfect for observing.
