Classical Nova ,V841 Oph has had two observations this week significantly fainter than any in it's approx 150 year history since explosion. These observations were made by two different observers. I propose to get at a minimum of one night of 4 V Johnson images 300 seconds exposure each, to acquire more data on this target. I don't know if this star is getting coverage now or not. I find no evidence for coverage. The W30 instrument would be a good choice , I believe. Observations should be made soon due to recent observed dramatic change in brightness of this star.

Target RA (H.HH) Dec (D.DD) Magnitude Telescope Observation Frequency Expiration Date Proprietary Term
V841 Oph 16.991769 -12.89089 4.3–14.9 No

This object should also most likely be removed from the Queue as the strange variability was already verified.
