Weather is good enough...for now.

I see the same thing that Shawn sees at the coord's Arne passed on:
18:59:32.95 +42:24:12.2 J2000

Using GSC 3127-1780 (approx mag 13.2)....  V358 Lyr is mag 16.0
unfiltered.  I can continue unfiltered time series for another three
hours (too low)...or cirrus clouds cut me off.

I'm also running a BVRI repeated sequence on the other scope.

I just took an unfiltered image of the field and believe that V358 Lyr is in outburst. I don't have any previous images to compare against but using the Downes online catalog it appears that there's an object at the correct location. Using the 14.0 mag star from the AAVSO sequence I measure the star at:

Nov 22.98 16.14CV

The FITS file is available at http://www.rollinghillsobs.org/v358lyr-001c.fit for inspection.

V358 Lyr is possibly in outburst - confirmation urgently required. In a single unfiltered CCD image obtained from the Bradford Robotic Telescope this evening I made the following measurement:

Nov 22.917 16.26C

I reported this to Gary Poyner, who measured the same image as 16.21C (both using the AAVSO chart).

However, we note that the position is very slightly West of the positon marked on the AAVSO chart, placing the suspect object half way between the marked position for V358 and the 175 comp. Unfortunately we only have a single BRT image and we cannot rule out a fault (doesn't look like a hot pixel), hence we cannot be sure that it is defintely V358 Lyr in outburst, thus the need for confirmation. Cloudy conditions at both my location and Gary's are preventing our confirmation.
