Swift Nova observation strategy

For Galactic Novae:

• If V_max < 5 : Observation daily, day 3 to 10 (or post X-ray peak if earlier)
• If V_max < 8 : Observation around 3 mags below maximum
• If detected :
  • If E(B-V) < 1 : monitor for SSS onset - weekly for fast novae, monthly for slow novae
    • If SSS present : monitor for SSS duration, frequency to depend on observed behaviour
  • Else : monitor monthly to end of emission
• Else : observe again in nebular phase
  • If detected : monitor monthly to end of emission

For Magellanic Cloud Novae:

• Observe MC novae with V_max < 11.5 at 6 and 9 months

All observations to be initially ~2 ks, though later observations may be longer if rapid variability or low quality spectra obtained.

This strategy has been developed as a guide rather than a fixed set of rules
