Photoelectric Photometry Newsletter

Reports of the AAVSO PEP Committee

I have included, in this newsletter, two reports by Howard J. Landis, the chair of the AAVSO Photoelectric Photometry Committee. One is the report which he presented at the 1997 Fall Meeting; it is therefore only a few weeks old. The other is the report which Howard presented at the 1997 Spring Meeting, in Switzerland. Because I did not produce a newsletter over the summer, it has not been published. It does, however, provide an excellent overview of the program, and I am pleased to include it here

Committee Report

Photoelectric Photometry, Fall 1997

Howard Landis, Chmn.

(CompuServe 71510,2355)

As of 1 October 1997, 17 AAVSO PEP observers have reported 2,716 observations in the fiscal year 1996/1997. The number of observations in our archive passed another milestone this year, reaching the 20,323 mark accumulated since 1983.

More PEP data is coming from overseas observers than ever before, this year it totals 640. Sergio Dalaporta contributed 430, R. W. Jones of South Africa contributed 180, and Hans Sorensen of Sweden contributed 30.

As in past years, Ken Luedeke assisted me with my work as archivist by entering data from observers who contribute data in hand written form. He also has done some tedious re- checking of the accuracy of data in STARPARM.DAT file that is used with the AAVSO data reduction program.

Jim Wood also has helped me with the matter of entering data for me. These two colleagues are very much appreciated for their help.

Sergio Dalaporta is a co-discoverer of the variability of SAO 0331661 along with the Hipparcos satellite program. It has been used as one of the field stars on the-CH Cygni PEP chart.

Dr. John Percy is editor of the Photoelectric Photometry Newsletter for which all PEP observers are appreciative. He is a very busy person and we are blessed by the time he gives US. He helps by answering questions about non-program stars or observing problems and gives advice on the relative usefulness of collecting data on them.

If you are interested in contributing PEP data to the AAVSO, please contact me via E-Mail or regular mail, we need you.

Respectfully submitted,

Howard Landis
