22173 28 Jun 2022 @ 0852 --- K.Cooper Attempted eruption
22256 08 Jun 2022 @ 2229 09 Jun 2022 @ 0100 SantaFe108 Did not attempt an eruption or had visible water of any kind for the rest of the night. Occasionally, gurgling would increase in volume but did not amount to anything. Bulger pretty much went to sleep for the night.
21850 08 Jun 2022 @ 2039 08 Jun 2022 @ 2133 SantaFe108 Bulger had an eruption attempt every 2-5 minutes (averaging 3 minutes) during this period.
21845 08 Jun 2022 @ 1715 08 Jun 2022 @ 1828 Forestbewithyou Bulger was quite busy. Had many failed attempts at erupting. Apologies in advance for this long list: 1715, 1719, 1722, 1725, 1729, 1732, 1735, 1738, 1741, 1744, 1747, 1750, 1753, 1756, 1759, 1802, 1805, 1809, 1812, 1815, 1818, 1821, and 1825. Man my finger hurts now.
21835 08 Jun 2022 @ 1509 08 Jun 2022 @ 1516 Forestbewithyou Failed start at 1509 and 1515. Interesting note: Shortly after the 1515 fail, Bulger’s hole filled with water to about 1/2 full with mildly boiling water

21782 06 Jun 2022 @ 1215 --- Forestbewithyou Failed eruption… what a surprise
21783 06 Jun 2022 @ 1104 06 Jun 2022 @ 1107 Forestbewithyou Two failed eruptions at 11:04 and 11:07… Left after 11:07

21507 25 May 2022 @ 2310 25 May 2022 @ 2325 Micah Kipple Resumed it's repetitive eruption attempts every 3 minutes.
21506 25 May 2022 @ 2005 25 May 2022 @ 2140 Micah Kipple Approximately every 3 minutes, Bulger would grumble, boil, splash, and surge up to a foot above the rim for about a minute.
21040 19 Apr 2022 @ 1350 19 Apr 2022 @ 1445 RMichaels Splashed every few minutes for durations of 30-90 seconds. Some splashes ejected water from the crater, so the activity could technically be considered a long series of weak minors. After observing for a while it just seemed like pre-play building up to the next major. The intervals were not consistent like long series of minors observed in prior seasons.
20727 18 Jan 2022 @ 0952 18 Jan 2022 @ 1232 Graham No eruption during this period.

18585 22 Jul 2021 @ 1215 22 Jul 2021 @ 1700 SteveO 1215 to 1700 no Buger eruptions occured.
18384 12 Jul 2021 @ 1245 --- JarnoO (wc) One burst and done, "minor minor".

17830 15 Jun 2021 @ 1417 --- Craigmon99 New to me seeping vent on top of bulgers right shoulder and above front vent. If this is not new I will delete. Will add picture with better service
15670 21 Aug 2020 @ 1821 --- Forestbewithyou Appears to be post eruptive.

14083 21 Jan 2020 @ 1205 --- Graham Still no eruption.
