[vsnet-alert 9228] CHarts for V1280 Sco

[Sebastian Otero]

Dear colleagues,
With V1280 Sco having become a naked eye nova, I made a chart with PEP(V) comparison stars to observe it.
The chart is for chi Ophiuchi, an interesting GCAS star that after spending several years at maximum (V= 4.2) it has been the last couple of years around V= 4.6-4.7.

So, for NAKED EYE estimates:

For BINOCULAR observations down to 7.9 mag., I have added the nova to the (updated) RR Sco chart:

According to the nova development, it looks like these charts will do for several weeks.

Best wishes,
Sebastian.
