Dear AAVSOnet Team:
As recently discussed via email with a number of the AAVSOnet members, allow me to please
introduce my friends, Professor Adam Rengstorf and his undergraduate student, Kyle Herron.
They are not AAVSO members, but everyone has encouraged their submission in connection
with my own membership.
Their principal interest is this eclipsing binary:
RA = 06:11:32
Dec = +32:28:52.5
V = 11.16
DeltaV = 0.66
P = 0.591 d = 14h10m
Gary Walker has already attempted some observations for them using his instrument in
California, but an unexpected problem with Gary's filter wheel may be inhibiting progress.
Kyle and Professor Rengstorf will welcome data from any instrument available. Please
advise us if the cadence, etc., requested in their proposal (immediately below) is possible
Note that Kyle has suggested observing windows on March 6-7, 8-9, and 9-10, Pacific Daylight
Time, and he can also generate others.

This observing campaign proposal is for the AAVSO and is being proposed by Kyle
Herron and Dr. Adam Rengstorf of Purdue University Northwest. We can be reached at
email@example.com and firstname.lastname@example.org respectively. We seek to observe the EP Aur
(Epsilon Aurigae) system, a system in the VSX. The campaign is to assist in completing a senior
research project which is needed to obtain a bachelor’s degree in physics from Purdue
University Northwest. A majority of its phase has already been documented, but due to poor
weather near our observatory, we cannot get any further data on the phases we still need for
this system. We wouldn’t need much time at all to observe the system because we are only
looking to observe the portion of its phase from 0 to 0.15, and 0.77 to 1. Upcoming times for
imaging are March 6th at 11:00 PM PDT to March 7th 5:00 AM PDT, March 8th at 6:00 PM PDT
to March 9th at 12:00 AM PDT, and March 9th 10:00 PM PDT to March 10th 4:30 AM PDT. As
far as the cadence, it should be the same each night, and done in nightly snapshots of one
image every 8 minutes. Minimum acceptable SNR is 100. CCD coverage is necessary as we use
AstroImageJ and its CCD Processor to conduct differential photometry for the project. DSLR
coverage and PEP coverage are not necessary. We would like visual observations, but given that
our V filter was recently discovered to be damaged, our previous observations have been unfiltered.
Thus, no filter is necessary, or the use of a "clear." Comparison stars are not specified and can be
chosen by the team. Spectroscopy is not necessary. We thank you for your consideration and assistance
with our research.
