In the early 1980’s, the AAVSO established a formal photoelectric photometry (PEP) observing program, administered by a PEP Committee, and guided by Janet Mattei and me. It built on three decades of previous AAVSO activity in PEP. At about the same time, the AAVSO established the PEP Newsletter, as a vehicle for providing instructions, information, and feedback. We also have a webpage that can be found under “committees” on the AAVSO website.
The PEP program flourished, as I shall outline below. In the last few years, however, the program has been taken more and more under the wing of AAVSO HQ, for a variety of reasons – not the least of which is because AAVSO Director Arne Henden is an acknowledged expert on photoelectric photometry!
It is therefore appropriate that, from now on, PEP instructions and feedback will be issued by AAVSO HQ as it is for most other variable star observing programs. But, with Arne’s permission, I am preparing one last PEP NL to offer my historical perspective.
