ASASSN-21tp

ASASSN-21tp --- ------- 8:46:11.18 -47:28:14.3 2021-10-21.33 13.84 SDSS DSS VIZIER ------- outburst from a previously non-variable star, matches to GAIA DR2 G=13.6, The ASAS-SN light curve for the last 300 days, the big spikes near g=12 are data artifacts.

Very unusual object.

Basic data:

2MASS 084611.130 -472813.69 (2000.0) 12.322 12.041 11.995 084611.124 -472813.65 (2000.0) Gaia_DR2_5329521945789287040 plx=0.964(0.015) dismod=10.1 pmra=-5.781(0.028) pmdec=9.573(0.027) G=13.602 BP=13.987 RP=13.045 084611.123 -472813.65 (2000.0) Gaia_EDR3_5329521945789287040 plx=0.986(0.011) dismod=10.0 pmra=-5.743(0.013) pmdec=9.598(0.013) G=13.593 BP=13.971 RP=13.034

No "outburst" in ASAS-3. ASAS-SN data suggest 5-d period during the current brightening. This reminds me of ASASSN-21gk and ASASSN-20da, which may represent a new type of variable stars (ATel 14593).
