The O9.7IIIe star HDE 245770, nicknamed Flavia, is the optical counterpart of the X-ray pulsar A0535+26. On February 5, 2011 at the Loiano 1.52 m telescope from UT 18hh 40mm 40ss we performed optical B, V spectrophotometry of HDE 245770 and starting from UT 18hh 51mm 11ss to 19hh 15mm 37ss we performed optical spectroscopy in the range 330 - 785 nm [Delta(lambda) from about 0.4 to 0.3 nm] by using the BFOSC (Bologna Faint Object Spectrograph & Camera).

Abstract
The O9.7IIIe star HDE 245770, nicknamed Flavia, is the optical counterpart of the X-ray pulsar A0535+26. On February 5, 2011 at the Loiano 1.52 m telescope from UT 18hh 40mm 40ss we performed optical B, V spectrophotometry of HDE 245770 and starting from UT 18hh 51mm 11ss to 19hh 15mm 37ss we performed optical spectroscopy in the range 330 - 785 nm [Delta(lambda) from about 0.4 to 0.3 nm] by using the BFOSC (Bologna Faint Object Spectrograph & Camera).File allegati a questo prodotto
