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.
March 15, 2018: Evan A. Rich (Ph.D. candidate, University of Oklahoma), and Drs. John Wisniewski (University of Oklahoma), John Tobin (University of Oklahoma), Carol Grady (Goddard Space Flight Center), and Mike Sitko (University of Cincinnati) have requested AAVSO assistance in monitoring the bright (6.9 V) Young Stellar Object NSV 24045 (HD 163296) from now through September 2018.
