Alert Notice 641: V1490 Cyg multiwavelength campaign

July 24, 2018: Dr. Dirk Froebrich (University of Kent) has requested AAVSO observations to support their upcoming observations of V1490 Cyg. He writes:

"Background: We have recently discovered that the young star V1490 Cyg (situated in the Pelican Nebula IC 5070) is periodically occulted by material in its circumstellar disk(*). Our light-curves indicate a period of about 32 days, and the obscurations are comparable to UX-Ori type eclipses.
