根据极红光的光学观测，M8.5 天体 SSSPM J0109−5101 最近被证明既是周期性变星又是耀斑变星。这里报告的超过 16 小时的近红外 (NIR) 监测未能显示任何变化。同样，在对其他三个可疑光学变量的强化监测中也没有检测到近红外变化。本文还报告了几周内监测的六个目标的光度测量，以及不同时期的密集监测的比较。仅在一种情况下，
The M8.5 object SSSPM J0109−5101 has recently been shown to be both a periodic and a flaring variable, based on optical observations in the extreme red. More than 16 h of monitoring in the near-infrared (NIR) reported here failed to show any variability. Similarly, no NIR variability could be detected in intensive monitoring of three other suspected optical variables. This paper also reports on photometry of half a dozen targets monitored over a few weeks, and on the comparison of intensive monitoring at different epochs. In only one case, that of the
