In previous cases where there were OM2 temperature transitions, Gravity Spy users had noted a specific glitch class (example 1) that is present for ~tens of minutes after the transition begins. This issue was also previously noted in alog 71735. Specific times where OM2 transitions were correlated with Gravity Spy glitches are listed in this comment. 

With this morning's OM2 heat-up (see alog 78573), these glitches were noted again. This can be seen in these example gravity spy subjects (example 2, example 3). This behavior can also be seen in the glitch gram for the relevant hour near 300 Hz (the OM2 transition began at 12:30 UTC). 

More notes from Gravity Spy users about this glitch class (referred to as "bike chains") can be found on this zooniverse talk page. Many thanks to all the volunteers who contributed to these investigations!
