The TAC recommends at least one observation per night.

Sounds good, go for it, at least BV, U and an I helpful.

V0462 Lup

(4603) Ray Tomlin — July 4, 2025, 2:27 a.m.

V0462 Lup (ASASSN-25cm) and HR Lup are both saturated in the images from BSM S5. They show up in VPHOT at grey and do not compute. Exposures are 10 seconds V and 20 seconds B. Suggest that you cut the exposures to 6 seconds V and 12 seconds B. The 60 second V and 120 second B exposures are way to long.

Exposure gets auto-adjusted as needed. Check next run.

The long exposures are meant for use when fainter. Report when short exposures are no longer working.
