    There has been a report of a very rare outburst of the UGWZ star PR Her on May 7 at 13.6 visual. The previous bright outburst occured in November 2011, although there have been sporadic sightings since then, but all below mag 15. If anyone can help confirm this outburst, the VSS would be very grateful.

    It’s position is…

    RA 18 08 04.44 Dec +38 46 17.3

    A chart and sequence is available from the AAVSO VSP (https://app.aavso.org/vsp/)

    A 157 star lies very close South West to PR Her, so some care should be taken.

    Thanks,
    Gary

    Gary,

    I’m on target now and not seeing it – unless its very, very close to the 15.7 star and the two appear merged.

    Could it have faded already?

    EDIT: Image attached. Pixel=1.54″ so field ~25arc min wide.

    Hi Gary,

    I do not see it at 13.6. Here is a 120 s V-band exposure of the field. It is supposed to be right next to the marked 15.86 star.

    On 25minutes worth of frames I am seeing something very dim and (on my frame) at the 7 o’clock position from the 15.7 mag star, but that seems slightly out of position compared to the AAVSO chart. Is that it?

    Likewise – negative for a PR Her outburst (8 May, 21:48 UT)

    Yes, nothing there that I can see.

    Looks like a false alarm – which is very disappointing. Thank you all for taking the time to check. Really appreciated.

    Just had a look at the area- I identified the stellar field quite quickly from the AAVSO chart. I couldn’t see the nova with my 12” Newtonian, although skies here are a little hazy now.
