37928 11 Nov 2024 @ 0653 --- JarnoO (wc) Attempted #2 for about half a minute beginning late 0653. Dense, sustained steam and splashing. Remained restless thereafter - looked like North Goggle late into a major. Calmed down after 0710 or so.
34351 26 Apr 2024 @ 1325 --- DanS Splashing and depth charge noises from main cone. All side vents dry and quiet. Large splash seen on webcam about 20 minutes ago.

27034 12 Jul 2023 @ 2030 --- minissa Wasn't sure this was worth reporting, but at about this time, we walked up on Aurum and it was as though someone had turned off the water. Some weak splashing, but the small, vigorous sputs that play continuously when Aurum is in pre-pay were absolutely dry. I didn't know if this was normal since its renewed activity, ,when all bets are often typically off at times like these. Hope someone can do something with this! Edit: I see that after I posted, someone had recorded a time right before we arrived.
26799 03 Jul 2023 @ 0924 --- Mikemcc all quiet.was actively bubbling an hour ago. probably had an eruption in the last hour.

26157 08 Jun 2023 @ 1248 --- K.Cooper No eruption yet. Vents have water, 3 is erupting in cycles. Nothing really impressive.
26145 08 Jun 2023 @ 0633 --- Graham Splashy, no eruption recently. Water in all side vents, #1, 3 and 4 splashing.

26061 05 Jun 2023 @ 1425 --- SantaFe108 1 and 3 are ie, 2 has water, and 5 is occasionally blooping. Base water level in the cone is visible with some splashes putting water out of the cone.
26045 05 Jun 2023 @ 1055 --- K.Cooper 1, 2, 3, 5 active. A few good Aurum splashes
26017 04 Jun 2023 @ 1520 04 Jun 2023 @ 1525 aferrara 1,3,4,5 erupting periodically, standing water in 2

25842 28 May 2023 @ 1542 --- Dan A Nice splashing at times, 3 o’clock bubbler is spitting, nothing visible in other bubblers.
25807 27 May 2023 @ 0547 27 May 2023 @ 1714 User34 Boardwalk wet, splashing in cone. Started looking more promising for a couple hours around 1400, but no eruption yet.
25814 27 May 2023 @ 1034 --- ltgangi reviewed the GOSA Overnight and thought that 04:51 this morning looked like a possible aurum, maybe someone else could take look
25806 26 May 2023 @ 2130 --- Graham NO AURUM YET.
25801 26 May 2023 @ 1403 --- Graham 7.5h in and splashing nicely for a long time. 1823 ditto, only later.
25792 26 May 2023 @ 0615 --- Lizzysa Vent 3 splashing; robust bubbling
25771 25 May 2023 @ 0556 --- Graham Splashing but doesn't look quite ready to go. Side vents just steaming.
25418 14 May 2023 @ 1136 --- SantaFe108 Periodic splashing inside the cone, Side vent closest to boardwalk is active.
25339 06 May 2023 @ 1645 --- SantaFe108 Periodic boiling in cone. Side bubblers are active. Brine flies are perusing the bacteria mat infront.
25260 28 Apr 2023 @ 1253 --- DanS No change. Periodic low splashing.
25210 22 Apr 2023 @ 1200 --- DanS Periodic splashing like last year
24842 08 Jan 2023 @ 1333 --- Graham Splashing in cone, occasionally reaching the rim. Snow in the runoff channel.
24610 30 Oct 2022 @ 1205 --- SantaFe108 Every couple minutes would vigorously splash above the cone. Side bubblers splashing. Same as previous reports.
24229 05 Oct 2022 @ 0931 05 Oct 2022 @ 0942 DanS Periodic splashing that reaches outside cone. About the same as last report.
24193 03 Oct 2022 @ 1127 03 Oct 2022 @ 1149 DanS Boiling and splashing in cone. Every couple of minutes splashing becomes vigorous enough to splash beyond cone rim. Two side bubblers active.
24087 25 Sep 2022 @ 0750 --- Graham Platform and runoff channel are completely wet.Splashing in the vent as usual with side vent active. No wetness visible on the railing or boardwalk.
23458 28 Aug 2022 @ 0845 --- RMichaels Geyser egg pool is again drying up. There is water on Aurum's platform, but it all seems to be coming from the satellite vents.
23210 15 Aug 2022 @ 2100 --- RMichaels Platform around Aurum is wet all the way to the runoff channels, though water is not flowing out of the pool in front of the vent. Satellite vents don't look to be pushing out enough water to account for it, either. No rain today. Aurum is occasionally splashing above the cone.
23176 14 Aug 2022 @ 1205 --- Ben VL Platform area much wetter than it has been. Some water in the left channel going out towards the marsh area. Guessing from the rain, but it might be nice to check the logger.
23123 09 Aug 2022 @ 0930 09 Aug 2022 @ 0935 c.barwin Aurum splashing ranged from out of sight to just above the cone rim. The splash pool had water that covered the geyser eggs and was mostly clear. The side vents were pooling water with the exception of the one at the 4 o'clock position. 1 and 3 o'clock vents were actively pushing water and 5 o'clock was mostly holding a pool with occasional overflow. The 4 o'clock vent was in shadow yet appeared dry.
22175 28 Jun 2022 @ 1510 --- aferrara Catch basin with eggs totally empty and dry
21318 16 May 2022 @ 1447 --- Brando One vigorous boil over the rim but sadly that was all
20749 22 Jan 2022 @ 1354 --- K.Cooper Just confirming and continuing what has been noted already. Small boiling inside of the cone but very little water outside. One of the side vents is active with some water coming out. Other side vents and the side pool have yellow and brown Cyanobacteria growing in and around them.
20673 11 Jan 2022 @ 1300 --- Graham No signs of recent eruptions. The runoff channel is snowed in, snow on boardwalk and the railing.
20231 30 Oct 2021 @ 1803 --- K.Cooper (Wc) Lots of stronger splashing well over the cone, a few of them made me go "wow."
19979 14 Oct 2021 @ 1400 --- Ben VL No excessive melted areas in the snow. BW still covered in snow too. Aurum looks about the same as it has most of the summer; mostly quiet, gentile splashing sometimes outside of the crater, and #3 bubbler oozing out water and bubbling gently. Not going to rule out the possibility of an eruption, but unfortunately the supporting evidence is a bit weak. See what the logger says.
18915 13 Aug 2021 @ 1230 --- Suzanne No obvious changes observed during and after the recent activity from Giantess. Two of the side sputs are constantly boiling and there is occasional boiling and splashing from the vent (but no cone-filling boils).
18024 22 Jun 2021 @ 1628 --- Graham Water a bit lower and less active.
17680 11 Jun 2021 @ 1020 --- TheHikingDude High water and periods of vigorous boiling. Tried to erupt a couple times before slowing to a halt.
17564 08 Jun 2021 @ 0633 --- Graham Splashing nicely in vent but water level is slightly lower than recent observations. May have gone overnight.
17136 19 May 2021 @ 1456 --- BobInSLC post eruptive, wet boardwalk
16879 17 Apr 2021 @ 1216 --- User34 Splashing confined to the cone, standing water level out of sight. Side vent 3 splashing but not pooling

15662 20 Aug 2020 @ 1945 20 Aug 2020 @ 2200 William Aurum being Aurum... no eruption during this time.
15636 18 Aug 2020 @ 1618 --- Suzanne post eruptive
15584 15 Aug 2020 @ 1803 --- Suzanne post eruptive. probably went a half hour or more ago. boiling at depth, no surface water.
15128 30 Jul 2020 @ 1930 --- William post eruptive, huffing, runoff channels beginning to dry up from previous eruption.

14719 24 Jun 2020 @ 0825 --- William post eruptive, huffing
14235 25 May 2020 @ 0838 --- Suzanne post eruptive
14180 04 May 2020 @ 1308 --- underarockphoto Both Aurum entries here only show steam on the static webcam. The weather this morning was highly conducive to steamy conditions. From my observations both entries are questionable. IMHO both should stay up as "wc ie ?" with a comment about it being on the static cam to at least leave a record that Aurum could have short intervals, or could totally fake you out.
14146 02 Mar 2020 @ 1400 --- JarnoO probable #2 in series, with 1356 ns as initial. Huffing @ 1407, may have been some water in there too (normal behavior post-eruption?).

14097 23 Jan 2020 @ 1037 --- Graham No Aurum yet. Not splashing well enough either.
14093 22 Jan 2020 @ 1202 --- Graham Splashing like it wants to erupt.
14090 22 Jan 2020 @ 0751 --- Graham Post eruptive steam huffing with occasional water droplets thrown out. erupted recently.
14086 21 Jan 2020 @ 1731 --- Graham No Aurum yet.
14076 20 Jan 2020 @ 1454 --- Graham Splashing as if it wants to erupt.
