## Three solar eruptions heading to Earth
Three coronal mass ejections erupted from sunspot region AR4549 on Oct. 6 and Oct. 7.
## First CME expected to arrive Oct. 9
NOAA's Space Weather Prediction Center forecasts the most significant CME to reach Earth on Oct. 9.
## Second CME possible Oct. 9
The second CME could deliver a glancing blow around the same time as the first.
## Third CME expected Oct. 10-11
A third CME erupted on Oct. 8 and could arrive around Oct. 10-11.
## Auroras visible in northern US
NOAA's aurora forecast suggests auroral activity could be enhanced across northern North America.
## Southern states may see auroras
If the incoming CMEs interact favorably with Earth's magnetic field, auroras could reach as far south as New York and Idaho.
## When to look for auroras
Forecasters predict minor geomagnetic conditions between 11 p.m. and 2 a.m. EDT on Oct. 8-9, followed by a possible moderate peak between 5 a.m. and 8 a.m. EDT on Oct. 9.
## Key takeaway

Three coronal mass ejections from sunspot AR4549 may enhance northern lights visibility across the northern US this weekend.
