We report the discovery of the new long-period X-ray pulsar SRGAJ204318.2+443815/SRGeJ204319.0+443820 in a Be binary system. The source was found in the second all-sky survey by the Mikhail Pavlinsky ART-XC telescope on board the SRG mission. The follow-up observations with XMM-Newton , NICER, and NuSTAR allowed us to discover a strong coherent signal in the source light curve with a period of ∼ 742s. The pulsed fraction was found to depend on an increase in energy from ∼ 20% in soft X-rays to…

TLDR
The execution of a lunar shadow intercept and the conduction of an observing program from a Boeing 747-400 ER aircraft over the Antarctic interior permitted the previously unobtainable to be accomplished.
