Hi Berto,

I cannot confirm you observations. I observe it in time series and find it at about mag 15.8 with a slow decline. That fits into the LC as from the AAVSO. Most of the data are my observations. I can clearly see a star at the position of DDE 99.

Regards,
Josch

DDE 99 is not visible on observations made at CBA Kleinkaroo around UT 2017 July 14.9. Limiting magnitude around 19.0

I will give it a try the next nights.
I am traveling hence data submission will be delayed.

Dwarf nova DDE 99 = GALEX J220630.7-524419 has developed the full outburst, as expected.

  20170707.6756  18.26CV  T32
  20170708.6710  16.54CV  T32  Rising
  20170710.5963  14.91CV  T32  Outburst
  20170710.5999  14.90CV  T32

The night of July 09 was missed due to clouds in Siding Spring. Data from South Africa and Southern America would be helpful to determine the peak time and maximum magnitude.

The current outburst should be a superoutburst. Time-resolved photometry is encouraged. The distance from the nearly full Moon is 40 degrees.
