New year aurora

2025 kicked off to a great start with a spectacular aurora on the night of Jan 1, 2025. Two CME's left the Sun a couple of days earlier and were Earth directed. The first was predicted to arrive New Year's Eve Australian Eastern Daylight Savings Time (AEDT). The leading edge arrived as the sun was rising. Activity continued all day. The first CME charged up the atmosphere. When the second CME hit late afternoon on Jan 1, there was plenty in the tank and the display persisted all night. This video starts just before the end of astronomical twilight, 10pm AEDT [1100UT] and continues all night, 400 minutes at 1 frame per minute, until 20 mins after the commencement of astronomical twilight at 0452 AEDT [1752UT]. There were two peaks of the storm. One was between midnight and 0130 AEDT, the other from 0346 AEDT into twilight.
