Alert Notice 607: MASTER OT J132104.04+560957.8 photometry urgently needed for XMM observations

Active Dates: Dec. 1, 2017 – Dec. 6, 2017


Abstract:

Dr. Mark Kennedy requests AAVSO observers' assistance in providing optical coverage of the polar MASTER OT J132104.04+560957.8 in support of observations with the XMM-Newton satellite scheduled for December 3, 2017.

Justification:

The XMM-Newton observations themselves will not include an optical component, so photometry provided by AAVSO observers is essential for the interpretation of the X-ray data. Photometry around the time of the X-ray observations is required to accurately construct an orbital ephemeris, and to relate any peculiar behavior seen in the X-ray light curve with the variations in the light curve produced by AAVSO volunteers.

Requested Data Types:

Photometry



Spectroscopy Lines:

No spectroscopy lines provided

Photometry Filters:

No photometry filters provided

Comparison Stars:

No comparison stars provided
