SPECIAL ALERT NOTICE TO PEP OBSERVERS

 

In a recent letter from Dr. Richard Wade of the California Institute of Technology, he wrote:

Alert Notice PEP #00: Special Alert Notice to AAVSO Photoelectric Observers [2337+56 Nova Cassiopeiae 1993] [V705 Cas]

Note: This Notice was originally titled:
SPECIAL AAVSO ALERT NOTICE TO AAVSO PHOTOELECTRIC OBSERVERS

It has been given the somewhat odd name "Alert Notice PEP #00" in 2016 so it will fit in with the other special PEP Alert Notices created by Aaron Price in 2001-2004. Eventually all of these special PEP Alert Notices will be renamed to something more consistent with Alert and Special Notice procotols. EOW 5/5/2016

Alert Notice PEP #0: Multiwavelength monitoring of 2349+28 II Pegasi

October 4, 1991

Note: This Notice was originally titled:
SPECIAL AAVSO ALERT NOTICE TO PHOTOELECTRIC PHOTOMETRISTS MULTIWAVELENGTH MONITORING OF 2349+28 II PEGASI

It has been given the somewhat odd name "Alert Notice PEP #0" in 2014 so it will fit in with the other special PEP Alert Notices created by Aaron Price in 2001-2004. Eventually all of these special PEP Alert Notices will be renamed to something more consistent with Alert and Special Notice procotols. EOW 10/27/2014

PEPObs user guide

PEPObs was developed from legacy code used to reduce photoelectric photometry submitted to the AAVSO PEP program.  We have retained most of the original fields for backwards compatibility with old PEP reports.  What follows is a guide to  fields in the online form with formatting instructions.  In the examples, the quotes ("") should not be included.

Alert Notice 476: Multicolor photometry of triple system b Per requested

January 4, 2013: Dr. Bob Zavala (U.S. Naval Observatory, Flagstaff) has requested AAVSO assistance in obtaining multicolor photometry of the bright triple system b Per in order to prepare for and detect a possible eclipse of the AB components by the C component predicted for 2013 January 23. At 4.5V, b Per, which is also a radio source, is an excellent target for photoelectric photometrists and DSLR observers.

Message from the Editor

Once again, photoelectric photometry was well represented at the AAVSO Fall Meeting, held this year in Chicopee and South Hadley MA, with Tom Dennis and Ron Zissell as hosts.

Alert Notice 440: PEP Observing Campaign on P Cygni

May 17, 2011:  Ernst Pollmann, an active spectroscopist in Germany and leader of Active Spectroscopy in Astronomy, has requested the assistance of AAVSO photoelectric photometry (PEP) observers in a campaign to observe the S Doradus variable P Cygni through the 2011 observing season.

PEP data are needed for correlation with spectra of P Cyg obtained by Ernst and other spectroscopists as they study this very interesting star.
