AAVSOnet telescopes in New Mexico have made two observations of ER UMa this week marking the start of this star’s observing season. As noted above, the next superoutburst may be around Oct 1 but could be later by a week or so as ER Uma does appear to vary its super cycle period between 45 and 55 days.
For UK observers, the star is very low in the north by north west sky in the evening. In the unsociable early morning, it does rise about 30 degrees above the horizon before dawn.
More details on ER UMa were presented in VSS Circular 188.
