AAVSO Alert Notice 587
Observations of FI Vir (Ross 128) needed this week
July 17, 2017: Dr. Abel Méndez (University of Puerto Rico at Arecibo) has requested AAVSO assistance in follow-up observations of the flare star FI Vir (Ross 128) subsequent to his radio observations obtained yesterday (July 16) with the Arecibo and Green Bank (GBT) telescopes and the Allen Telescope Array (ATA).
Photometry, with as high precision as possible, is requested, beginning now and continuing through Friday, 2017 July 21. V and R are preferred but unfiltered is also all right. Two or three snapshots per night are needed. FI Vir, with a range of U = 13.82-14.26, is V ~11.2.
Coordinates: R.A. 11 47 44.40 Dec. +00 48 16.4
Charts: Finder charts for FI Vir with a comparison star sequence may be created using the AAVSO Variable Star Plotter (VSP).
Submit observations: Please submit observations to the AAVSO International Database using the name FI Vir.
This campaign is being monitored on the AAVSO Observing Campaigns webpage and is being followed on the Campaigns and Observation Reports Forum at https://www.aavso.org/fi-vir-ross-128-o ... g-campaign.
This AAVSO Alert Notice was compiled by Elizabeth O. Waagen.
