22410 08 Jul 2022 @ 1830 08 Jul 2022 @ 1904 minissa Noticed a tiny sput in the catch basin /berm {ie pool of standing water within the berm} of LB. Eruption is all of 2 inches and is difficult to see without binoculars but seems to be a tiny perpetual spouter. Didn't know if it had been noticed before.
21393 20 May 2022 @ 1942 --- BillJ Several brief eruptions around this time; intervals typically `1 minute but couldn't get exact times.
21382 20 May 2022 @ 0830 20 May 2022 @ 1013 Micah Kipple Little Brother is erupting 5-10 feet high every 30-70 seconds (with outliers on both sides) . Preliminary observations and timing this morning suggests that it likes to slow down after an eruption of 3 crater. Detailed eruption entries and further observations to follow.
21060 23 Apr 2022 @ 1705 23 Apr 2022 @ 1735 DanS Little Brother continues to erupt every minute or two.
21002 18 Apr 2022 @ 1739 --- steve Little Brother appears to be erupting about once a minute. GT tends to assume the second eruption is a secondary report of the eruption a minute earlier.
20989 16 Apr 2022 @ 1514 16 Apr 2022 @ 1519 steve Little Brother appears to be erupting once to twice a minute to 6-10 feet. So far all I have seen are single bursts.
20777 02 Feb 2022 @ 1022 --- Art-P erupting every 1 1/2 to 2 minutes
20747 22 Jan 2022 @ 1315 --- K.Cooper Continuing eruptions every minute, same size.
20746 22 Jan 2022 @ 0958 --- K.Cooper Continuing to erupt roughly every minute to two minutes. Roughly the same size as yesterday.
20743 21 Jan 2022 @ 1426 21 Jan 2022 @ 1442 aferrara Continued eruptions around once per minute. More frequent when Three Crater tries to start.
20741 21 Jan 2022 @ 1359 --- aferrara Tiny splash
