Alert Notice 703: TCP J21040470+4631129 images, photometry, and spectroscopy urgently requested - REVISED

Active Dates: April 1, 2020 – April 30, 2020


Abstract:

Dr. Juan Echevarria (Instituto de Astronomia, UNAM) has requested AAVSO observers' assistance in acquiring images and carrying out spectroscopy and photometry of the WZ Sge cataclysmic variable TCP J21040470+4631129, which is undergoing a superoutburst. Please continue images, photometry, and spectroscopy of TCP J21040470+4631129 at least through the end of April 2020.

Justification:

Photometry in V is also requested, as most large ground-based telescopes are closed at present. High speed photometry is requested to analyze superhump behavior. TCP J21040470+4631129 is a morning object, but knowing the magnitude is crucial so photometry is essential. Spectroscopy focused on H alpha is also encouraged.
